Deadlier Than Chucking Nuns – And Legal!

In my last rant about the stupid “weapon” law in Germany, I mentioned that nuns chuckers are illegal to even own and use as training equipment. Similar restrictions apply to kusari, monkey’s fist, and several other weapons that are essentially rope/chain with a metal weight attached to the end.

Today I would like to expound more on the stupidity and nonsensicality of this law. Because when I mentioned that I used to train with nunchaku, what I did not mention was how I started. I did not have nunchaku at first, and it took me a long time to make them because I first had to get my hands on some suitable wood, then a piece of chain, then to figure ut how to make them, etc. This shortly after the fall of the iron curtain when buying even simple things still could be challenging, the internet did not exist and I was a kid with zero money anyway.

But what I did already have was jumping rope. So I took it, tied several knots on the rope to adjust the distance of the handles at the desired length, and voila! I had perfectly suitable training nunchaku. Not for training combat, but certainly for training flourishes, which is what I did. It also had the added benefit that the handles did not have too much mass to them, so even when I hit myself (which did happen at the beginning), it was never anything even remotely dangerous. It was also a great workout, much more fun than using the jumping rope for its original purpose. And then when I finally got some real nunchaku, I already had some muscle memory to use them safely. Which I did. And since the nunchaku weighed more than the jumping rope, the workouts got even better.

And remember, the reason why nunchaku are banned in Germany is that they can be used as an effective garotting weapon (no they can’t), and the reason for banning ropes/chains with weighted ends is because they are highly dangerous impact weapons by generating momentum by slingshot/whip effect (at usual length,  they don’t, it is just angular momentum like with a hammer, the only benefits to the wielder are that there is no shock transfer to the hand and compact size).

But guess what – jumping ropes, even with handles from metal and adjustable rope length, are legal in Germany! A thing that would be both much better for garotting than nunchucks and that could generate a lot more momentum than an illegal monkey’s fist keychain!

I will leave you with that thought.

Unexpected (But Not Surprising) Benefit of Tumbling Blades in Sand

I just might tumble all blades from now on, even those that I will mirror-polish manually afterward. Because after two-three days of tumbling, an interesting phenomenon appears. Something that is not surprising when you think about it, but I did not in fact expect it upfront.

It is difficult to snap a picture of it, but here it is visible – the blade is all shiny except that triangular shadow at the tang. That is an area where the blade is not hardened.

In this specific case, this is OK. The tang should be soft and a soft piece of the spine, especially near the tang, also does not hurt. And because this blade will be blackened with oak extract, the visible difference in color should not be a problem.

However, there were two other blades, one from spring steel like this and one from N690, that had shown this discoloration in areas where soft steel definitively is not desirable – one about 2 cm at the tip and one ca 2 cm of the blade near the ricasso. Those were improperly hardened and I did not find out during the scratch test right after the quench, because most of the blade was OK.

That is quite useful and thus I really consider incorporating sand-tumbling not only as a cheap surface finish but also as cheap and easy quality control.

Not Tacticool, But Hopefully Cool

A friend tasked me with making a knife for their spouse. The spouse does not cook, so a kitchen knife was not an option. But they do occasionally go on a camping trip or a forest walk with the kids, so we eventually established that some sort of camping/bushcraft knife would be best.

The ideal material for a knife of this kind would be spring steel, but since it is unlikely that their life will depend on it, N690 should suffice and rust won’t be a problem. So I set to work and I have made this.

The blade is 160 mm long and 5 mm thick at the handle and tapers toward the tip. N690 steel, sand tumbled satin finish. The handle is made from rotten willow wood stabilized with green-dyed resin. It is a big boi – it weighs 300 g (and that is with the fullered blade and handle is lightened too by holes in the tang). A sharpening angle of 25° should guarantee that with occasional use, the blade will not need sharpening any time soon. Despite being thick, it is reasonably sharp and cuts well, because it has a flat grind all the way to the spine. It is balanced at the bolster, and it packs quite a punch, as a knife of this type should. And because the spine is so thick, it should withstand even some serious abuse should the owner decide to inflict it on the blade. Which I suspect they won’t.

The accessories are a ferrocerium rod and carbon steel striker as a fire starter (more for fun than real purpose, matches are better) and a sheath with a pouch for these. Theoretically the carbon steel striker is not necessary, but when testing it out, I got the subjective impression that carbon steel strikes better sparks from the ferrocerium rod. I might be wrong, I could not think up an objective test for that.

Making fullers by hand is very difficult, it will probably take several more blades before I get it right. I am currently wracking my head about how to make an accessory for my grinder that would make this difficult task just a tad easier. So far no success, just a few semi-functional, semi-failed attempts.

How Many Nuns Would Nunchucks Chuck…

… if nunchucks could chuck nuns?

I am going to ramble a bit about my pet peeve nonsensical weapon bans and regulations around the world. I am in no way a freedom absolutist in this regard. Weapons are dangerous objects that definitively need to be regulated, and the more dangerous a weapon is, the stricter regulations regarding its accessibility to people should apply. There should be background checks, aptitude tests, mandatory training, and licensing for all firearms. But banning hand weapons is useless and oftentimes downright silly and makes no sense whatsoever.

Take for example the titular nunchucks. I have trained with nunchucks as a kid, I have never hurt my self and I never broke anything either. It was great fun and it was beneficial to me. They are great for hand-eye coordination, great for training speed, and spatial awareness, and it was a good workout too. What it was not – despite me not knowing it at the time – was useful combat and martial arts training applicable for self-defense. Nunchucks are a terrible weapon, although they are better than nothing (not better than running away).

To my great surprise a few years ago, I have learned that nunchucks are banned in Germany. Not only to carry around but to own or manufacture. You will not find Karate or Kobudo class in Germany that trains in their use, not officially at least. That is daft, especially with the reason given – they can be used as a garotting weapon. Well, theoretically, maybe, but they would be awfully ineffective for that. That is not what they are designed for.

And since I have already sold knives to people in Germany, I have looked into laws regarding them a bit and those are too silly squared. Knives that can be opened with just one hand are banned to carry. Knife with a fixed blade can be carried if one is currently performing an activity facilitating its use – like fishing, hunting, or mushroom gathering – but I have read some stories about knives confiscated on the way to a forest, so it can depend on how pissy the policeman you have encountered feels that day. And balisongs are banned to even own, just like nunchucks. I did not dig too deep into that, but whatever the reason, it is just silly.

Because balisongs are really, really bad pocket knives. Their advantage over other pocket knives is that they are very easy to make, but that’s it. They cannot be made very sturdy, their very construction means the blade will be always a bit wobbly. They cannot have any meaningful handguard so when stabbing something with them, there is always the risk of your hand slipping on the blade upon hitting some resistance. And several other things make them bad. The only thing they are really useful for are the same things that other small pocket knives are useful for – cutting food, opening packages, and so forth.

When watching some random videos on YouTube recently I have learned that flails and maces are allegedly illegal in parts of Canada too. And again, I fail to recognize the reasons for this.

In the UK, the reasons given for these imbecilic weapon bans are to prevent gang violence. It does not seem to work. You can ban nunchucks and kusaris, but you cannot ban keychains. You can ban knives, but not screwdrivers. You can ban maces, but not spanners, and hammers – and guess what, the gangs are using these everyday objects exactly for that reason.

I suspect that these weapons were made illegal because they were portrayed as very deadly in 90s action flicks. If so, then legislators enacting these laws should learn the difference between a movie and reality. Bruce Lee movies are NOT documentaries!

But OK, when these laws are in the EU, they are very silly, but at least they are somewhat consistent with the overall culture. But when they are enacted in the USA, their silliness condenses into a black hole of daftitude.

Now one can say that nobody actually needs weapons like nunchucks, maces, or similar and I should shut up about this. I disagree, but I won’t argue against that right now.

 

Bobbin Lace: Peacocks

My mother had a “peacocks” period now and has made several. This was our classical collaboration where she bounced a few ideas of me, I then suggested some improvements, she has drawn it again and so forth until she arrived at a design we both liked. Two of them she has even changed after she has already done them in lace because they did not come out right.

All except the last one are approx A4 size, that last one is about half of the others.

Sharpenatrix

Walter Sorrells has recently made a video about a sharpening tool for his belt grinder, which gave me an inspiration for finally making my own. I have been planning to do this for a long time, but watching that video helped me to solve the final piece of the puzzle.

Walter Sorrells is of course not only a much more experienced knifemaker than I am, but he is also much better equipped. So my project has all the hallmarks of my handmade tools – it is crude and made from scraps.

I have started with a very rough sketch of the jaws and I have also spent some time calculating trying to establish various proportions whilst finding a compromise between stability (shorter arm is better) and consistent angle across the blade (longer arm is better).

© Charly, all rights reserved. Click for full size

Here you can see it in full when finished. Jaws for holding the blade are mounted on a ca 40 cm long 10 mm stick with a ball on the lower end. The ball goes into a socket at the end of an arm that can slide forward and back with regard to the belt, thus adjusting the angle at which the edge leans on it.

© Charly, all rights reserved. Click for full size

The 10 mm steel rod is recycled from our old heating oven. The plastic ball at the end is an old furniture handle. All the wood is recycled from an old bed.

© Charly, all rights reserved. Click for full size.

The jaws are made from 4mm mild steel and lined with 0.25 mm bronze held in place by means of double-sided adhesive tape. Near the tip of the jaws are two 5 mm pins that are screwed into the smaller jaw and slide into holes in the bigger jaw. They provide an end-stop to rest the blade against in order to fix it easier into the jaws and they also prevent them from wobbling.  The upper screw tightens the jaws and the lower one sets the distance between them, so I can vary it according to the blade that is being sharpened.

© Charly, all rights reserved. Click for full size.

Originally, I have planned to make the socket from wood and I expected it to take a lot of time. But I got a brilliant idea during the work to use a lid from a fabric softener bottle. It cracked during work, but I still could attach it to the arm with a  screw and a large washer. After that, I have covered the screw head with a piece of PVC flooring and after some consideration, I have also added two hard gaskets to keep the ball centered and to provide ever so slight resistance to movement.

The sliding arm can be fixed in position with a fastening screw salvaged from some defunct kitchen appliance from a long time ago and a galaxy far, far away, from times when things were made to last.

When the weather allows it, I will give the thing a coating of grey paint so it looks slightly less amateurish and also to protect the wood from moisture. And I will mark a scale on the sliding arm so I do not need to bother with measuring the angle.

I do not expect this to save a lot of time. I already sharpen knives on the belt grinder and it does not take me more than about five-ten minutes per blade. But it will make the job a bit easier and the angle should definitively be more consistent, which is a plus. I am not one who is overly concerned with sharpening angle, I think that anything between 15° and 25° works just fine for most knives, but consistency does have an influence on the durability of the edge. For example, the N690 steel that I am using for most of my knives allegedly should not be sharpened at a too steep angle (below 15°) because then it tends to chip and break. With this tool, I can at least be definitively sure that I won’t go any lower than that.

We shall see how it works. I do have a lot of knives that need sharpening.

Kitchen Knives Set – Part 8: I Just Could Not Stand It

It is several months since the last update on this project, and there are reasons for that. Some have to do with the project itself, some do not. One of the reasons that are directly related to the project was that I had difficulty finishing the knife stands because in the cold weather the boat lacquer that I have decided to use for finish took an absolutely inordinate amount of time to harden properly. So prepare now for a really long post about how I made the wooden stands for these knives.

The original plan was to make all woodworks from jatoba and black locust, thus making the stands from massive hardwood. But since I have made the handles from the rather rare and precious applewood, I had a very limited supply. Especially when it came to the spalted wood. So I stood in front of a decision – should I try to make the stands match the handles or not. And I have decided to give it a try and make matching stands. Which means getting a lot out of a little.

© Charly, all rights reserved. Click for full size.

First I started by cutting the cores of the future stands out of some scrap spruce wood, of which I have an overabundance. Where I needed a thicker piece, I have simply layered and trimmed the thinner ones until I got the size that I wanted, with a generous amount of wood on both sides of each blade, especially for the stands where two blades were meant to be next to each other.

This was the first time I have used expanding PU glue. PVA glue would have difficulty to set in my workshop, even with heating. This glue did harden within a few hours enough so I could safely take it indoors for the rest of the curing process.

After these cores were glued and cut to the final size, I have sanded all flat surfaces. Not very thoroughly, just enough that I do not get my hands full of splinters.

© Charly, all rights reserved. Click for full size.

And since I had to do with what little of the precious wood I had, I have decided to use thin boards/veneers for finishing. I have cut approx 5 mm thick slices of the wood on my bandsaw and with a bit of luck, I did get enough of each of the three types of wood that I have used for the handles to cover the stands. Mostly. I could have cut even thinner veneers, like 2 mm, but 5 mm did save me a bit of work later on.

© Charly, all rights reserved. Click for full size.

Most veneers were cut with the grain, but I have also cut several pieces across the grain. Those I have glued on the end of the softwood cores and only after that I have cut the slits for blades. For each blade a cut just as deep as the blade is wide, so each knife has a slot fitted exactly to it. I took two passes on the circular saw for each slit since I have cut them about 1-2 mm wider than the blades are, so the knives come in and out really easily without scraping the sides. That way at least I hope the probability of something getting stuck to the mirror-polished blade and scratching it later on in the stand should be reduced. I could not of course make the slits too wide, because then the point could get stuck in them.

Wherever veneers had to be put side-by-side, I had to carefully fit them together so the seams are as small as possible. In one case I also had to change the design of the stand since I did not have any veneers long enough and I did not want to link veneer strips lengthwise. Two strips beside each other do connect almost seamlessly and even when they are visible, they do not disturb. But a clear line across the grain or the pattern in the spalted wood would surely look at least odd.

To fit the veneers properly all around I had to first glue up two opposing sides, trim the excess, grind it to flat, and only then I could glue the other two sides. Trim and sand again and I got finished building blocks for the final products.

There were some minor problems – the spalted wood was soft and got chipped – so I had to fill in some places with resin mixed with sawdust and/or offcuts.

© Charly, all rights reserved. Click for full size

Then there was a lot of sanding. It made me glad to have a hand-held belt sander. I will probably have to buy an orbital sander too if I am going to make more of these.

© Charly, all rights reserved. Click for full size.

Since the resulting pieces had very sharp edges which would not look very well in combination with the rather rounded handles, I have decided to round them significantly. I did not use a router, although I do own one. Instead, I have just sanded all future edges down with 60 grit sandpaper over a soft sponge until they looked right, and then I have polished them.

© Charly, all rights reserved. Click for full size.

In one of the stands, the pieces were connected by big enough flat surfaces that I could reliably clamp it all together during curing, but int two of the pieces had to be connected by relatively small areas and at an odd angle, so I have used a piece of wood to drill holes for dowels to prevent the parts from shifting during the glue-up.

© Charly, all rights reserved. Click for full size.

And here they are, fixed to small boards for stability and handling during the paint job. I have decided to use boat lacquer for the stands because infusing such big pieces with resin would be very, very expensive. I did not expect it to take as long as it did though.

© Charly, all rights reserved. Click for full size.

After the first coat with highly diluted lacquer the grain and fungus patterns popped up on all pieces quite significantly. I have left it dry for two days and then gave it two more coats with diluted lacquer in two-days intervals to stabilize the soft and spongy wood as much as is possible. And after that, it was five-six more coats with undiluted lacquer, with a few days wait and thorough sanding between each coating. When the last coating was drying, I got tangled up for several weeks with other works, mainly in the garden, and only this last week did I get round to do the last hand sanding. I sanded the pieces in increasing grits up to 1000 and there I did stop because I wanted them to have the same satin finish as the handles.

© Charly, all rights reserved. Click for full size

I have modified my buffing compound for the stands, but it is still perhaps a bit too hard. It did buff the pieces nicely though, so I cannot complain. Too much. I did achieve my goal, which was to make the stands reasonably similar to the knife handles. There is a bit of difference in color because the handles are thoroughly infused with resin, but I do not think it is a problem and neither does anyone who has seen it so far (about 7 people).

And this week I finally got to the last step in this rather long project – making the stands to actually, well, stand. Out of the three, only one was big and heavy enough to be stable – the one from mostly healthy wood. For the other two, I did not have enough material to make them with a wide enough base, so I had to fit them with legs. I have considered several options and I have decided to go with a 6 mm stainless steel pipe. Aluminum would look cheap and brass would clash with the visible stainless steel tangs on the knives.

© Charly, all rights reserved. Click for full size

To drill the holes safely and at a proper angle, I have first made a little board that could be fixed to the stand at the angle I wanted it to be in one direction. In the depicted case, the board is at the angle the leg is supposed to be when viewed from above. Into that board I have drilled a hole at an angle it was supposed to go into the stand. Then I could fix this board to the stand by the simple method of copious amounts of paper masking tape and drill the hole safely and at the correct angle.

By the way, I did not do any measuring or sketching for this. The “correct” angle was established by eyeballing.

© Charly, all rights reserved. Click for full size

With that, I was still not done with this piece of wood. I have trimmed one end of it at the angle the leg will touch the ground and used that as a guide to filing down the end of the pipe flat-ish.

© Charly, all rights reserved. Click for full size

Gluing the legs with epoxy was pretty straightforward after that and they were already mostly – although not perfectly – flat against the plate.

© Charly, all rights reserved. Click for full size

They did need a bit of sanding to get them perfectly flat, but not that much.

And that is the project almost finished. All that is left is to sharpen the knives and make pretty pictures. Hopefully sometime soon. You can see here that I have also already begun the next batch of knives. Yup, that is how long it took for the lacquer to harden, I have managed to grind and harden ten new blades in the meantime.

The next – and last – post in this series will be pure cutlery porn. This is one of those rare instances where I think I have done a good job.

 

Grumpy Redstart

It is very rare that I get an opportunity to take a picture of male black redstart. I see them all the time, but they are restless and they never come to the feeder. This one was moving around the feeder, although he did not eat the seeds – he used the surroundings for vantage points to spot insects in the grass. And he stayed a few times in one place long enough for me to take a picture.

That last picture gives me the impression of an old grampa looking disapprovingly at me. Something about the line between the black and grey feathers above the eyes gives him that look.

Behind the Iron Curtain part 37- 1st of May

These are my recollections of a life behind the iron curtain. I do not aim to give perfect and objective evaluation of anything, but to share my personal experiences and memories. It will explain why I just cannot get misty eyed over some ideas on the political left and why I loathe many ideas on the right.


One of the central dogmas of the regime was the notion that everything is for the common workers, the laborers, and peasants. Those were deemed not only essential for the proper running of society (not wrong), sometimes to ignoring that intellectuals actually have useful functions too.

The International Worker’s Day was a state holiday, and we were taught at school a bit about the history behind it. Not much, as far as I remember, but the actual reasons behind the holiday were discussed and even in hindsight, most of them were valid then and are valid now.

However, as it is with authoritarian regimes, the good came with the sidedish of the bad and sometimes downright ugly.

1st of May was an official day off of work and school, so officially people were free to spend that day as they choose. In every town and moderately sized village, there was a procession and a speech by some party representative, but attending was not compulsory. In the sense “it is voluntary, but you have to go”.

I did not like the processions that much, because I do not like crowds and loud noises. But I did attend. I do not remember much, only two experiences come to mind at least somewhat vividly.

The first experience was an extremely strong feeling of embarrassment when our local firefighter truck was driving along the procession, shouting propaganda and encouragements for cheering from loudspeakers. I did not like it and even to my socially stunted mind, it was clear that nobody else liked it either. If the day is so glorious, if our country is so great and the party so beloved, why on earth do the people need to be egged on to cheer and shout slogans by an obnoxious a-hole with a megaphone? I did not put it in those words exactly, but those were my feelings.

The second experience was the chastising of one of my classmates who was not a member of Pionýr and whose family did not attend the parade one year. In a small town, this did not go unnoticed and our class teacher did call him out publicly during class for this. There were no other repercussions other than the public shaming, but I did not enjoy seeing that at all.

In both of these instances, I have subconsciously sensed a deep disconnect between the messaging we get and the true state of affairs. That cognitive dissonance was not particularly strong, but it was there and it was nagging. When the regime finally fell, a lot of the things that did not make sense to me as a child started to make sense later.

Later in life, I was surprised that much of what I have been taught to see as “Capitalist countries” also celebrate the holiday, oftentimes including the parades and speeches, but without the voluntary compulsory nature. I am afraid that in my mind this holiday will always be tainted, as it is in the minds of many of my generation.

What is The Situation in India – View of Indian Doctors

TLDW – It’s hell.

It looks like the Indian government made the same mistake that the Czech government has made – the first wave of the pandemics was so well handled that politicians got the feeling that it is all over now. And communicated this to the public, who were all too eager to believe it. And because India has both a lot more people than Czechia and fewer hospital beds per capita, the disaster is proportionally worse.

I have never expected to see the truth of the saying “you should not rest on your laurels” demonstrated in such a tragic way.

Medlife crisis is an excellent and entertaining science and health-oriented YouTube Channel. This video, however, is not of the entertaining and funny kind. I do recommend his other videos too.

A Dandily One

Dandelions in the vegetable patch are a nuisance, but in the lawn, they are a delight to see. For me anyway. They bloom soon after snowdrops and narcissuses and continue to do so well into the fall. Thus they are an important source of food for bees, butterflies, and all other kinds of pollinators.

This is not the first dandelion of this year in my garden, but it is the first one with multiple blossoms opening at once. Unfortunately, there were no insects to be seen anywhere right now, although I did see bumblebee queens scouting the garden for nesting places.
