When I first made this blade I left it in the coal too long and melted a big bite about 2" away from the tip. Luckily I had enough material to draw out a decent length and I completed the blade and move on. Shortly after I wished I had kept the melty part and just made the blade around it.
A few months went by and I decided I wanted to try and quench a hot blade in black powder and this is when the two ideas merged. I didn't really want to make a new blade just for the purpose of melting the back, seemed too contrived an idea. Without the risk of ruining a good blade, the concept had no teeth and the finished product would lack some depth. It had to be an already finished blade that I would destroy in an effort to improve its aesthetic. Sort of a creation through destruction ideology.
The black powder idea was just an experiment to see what would happen to soft melty steel when it interacts with an explosive. I might try thermite next time. Here's what happened.
after some normalizing and a polish with steel wool.
I will likely make a Santoku shape out of this and make it my travel knife.
this is after heat treating. Can't quite see the hamon as it's behind a layer of scale, but it's there and I may bring it out over time. I've already re-profiled the choil and brought the shoulder up 4mm.
I glued the thinner mokume to the handle then ground it flush. Ive been shaping the concaved upper portion separately. The two will be separated by a african blackwood spacer. Ive never used jb weld before but i did on this one. Really impressed by how well it holds up to heat.
