… but by no means a small knife.
Harvesting firewood from my coppice is a yearly task that requires a lot of chopping off thin branches and twigs. Currently, I am using an old chef’s knife for that, but it is getting pretty warped and worn-out because it was not meant for that kind of work. And a hatchet is too unwieldy for it.
So two years ago I tried to make a machete. And I failed completely, the blade warped in quench and subsequently snapped when I tried to straighten it. It broke near the handle, so I had a relatively big chunk of straight blade left, but I did not know what exactly to do with it and I had better work to do anyway, so I have just used it for various experiments – for etching and tumbling tests, etc. I learned a lot from the piece for my future projects, so it was not completely wasted. But it was still big enough to make a knife, and the surface was so pitted now that it was no longer suitable for tests. So I have decided to make a knife out of it after all.
I annealed about one-third and cut the tang out of it, then I have put the now 17 cm long blade in the tumbler with fine sand and let it run for a few days to clean the surface of most of the corrosion, although the pitting of course remained. I did not polish the blade afterward to remove the pitting since that would make it really thin. Instead, I have dunked it overnight in tannic acid (or, as per Marcus, Oak Drop Soup). It got a nice dark-grey-blue coating that way and a really mean rustic look. In combination with linseed oil, it should provide moderately durable and strong corrosion resistance. Only I forgot to etch a logo in it before doing all that, and now I can’t, so the blade is unsigned.
The handguard is from bronze and old bone, the handle from pickled black locust. When I am making sheaths, I will make one for this too. I must confess – I did not do a very good fitting job on the handguard, I did not want to waste too much time on this. And I have decided to let the bronze get a natural patina over time for the same reason. But since this is a working knife for me, any flaws are not a problem since nobody ever will complain.
I think it looks kind of nice and I am considering adding this type of knife to my repertoire as a bushcraft knife, with only slight changes in construction (full-tang instead of hidden tang). I am also considering adding a lanyard, although it is secure enough in the hand with this handle-shape. I have already tested it for its intended purpose and the blade coating is resistant enough to withstand wood-chopping. And if it rubs-off, it is easy to reapply. I really like how this turned out and I am glad I did not simply toss it on the scrap pile.
