I have made several pairs of these; they turned out surprisingly well and are an easy mold to work with, since it’s open and you can just pour the metal right in. The legality is questionable, unfortunately.
It takes a bit of work with a die grinder and a dremel tool to get the metal cleaned up, and I hate to admit that I got the zircon a bit off. [@kestrel, when you said “drill a guide hole and practice” that’s not what I did!] To make extra space on the palm-piece I altered the wax before I made the investment mold – I just melted a bit of sprue wax and packed it in then smoothed it down.
Polishing silver is very satisfying, though it leaves my hands an unattractive gray color for a while.
Now I need to make some damascus safety razor blades (supersized!) and I can really sport 80s bling.
I ought to be able to take down a werewolf with one punch from these.
These take a fair bit of silver (about 5 troy oz, or $250 worth) so I won’t be making many of them. On the other hand, I could whip them up in pewter pretty easily. The main headache is all the polishing. But it feels pretty good to walk around with some steel wool, buffing your knucks.
