Whee, so many positive responses! Thanks all for your kind words.
Yeah, I made these myself - I began with a rougly cut piece of HSS steel(these saw blades are so tough that oxy-acetylene torch can't cut them, plasma cutter had to be used!). Then angle grinder, Dremel, lots of sweat and some blood(and lots of swearing). I
melted three HSS drill bits when I was drilling holes for pins in the karambit. The handle part is annealed, but it barely helped...
My metalworking experience is very limited, almost none. I just took my time with these knives and I think it shows

Karambit? I can serve with a plasma-cut blank, I have a spare one. But the finished knife... well, pay me about 300 dollars and wait for a half a year - then, maybe, you can have one. Bankerai is a nasty thing to work with, splinters don't fester out, you have to pick them out with a needle and tweezers, one by one... Am I graphic enough?

I hate that wood for working, but it has a nice texture and it doesn't warp with time.
The Falcon will be probably up for selling or trading, I just don't have the "bond" to it. It is a pretty nice knife, in all probability it can be stabbed through a car door without severe damage and it is sharp enough to shave, but I am not very attached to it, so if somebody would offer me something interesting...
