Ive got a chrome-vandanium steel blade I cut in half to make a knife, still have half if you want it. I also have a high speed steel blade, but no idea on where it is.
I also have an old carbide.
If you want one, we can work out a trade.
It ticks me off when this kind of stuff happens. One of my neighbors is so bad about it that I freqently peek into his trash cans and occasionally ring the doorbell asking if I can take stuff from them. Its awesome sometimes, but I get mad when I miss something.
Carbide blades are decent. Not super good steel, but not low carbon either. Makes a decent throwing knife, but not much else. Throwing knives need to flex, not crack like high carbon. I think the blades I have are medium.
