Just a little to add, I purchased one of his neck knives and was very disappointed in it performance. When it arrived it would not shave hairs off my arm, it made 5 cuts through 5/8" manila rope, it was 1/2" shorted then advertised, the sheath that it came in was made of a really thin leather that would not hold the blade in. All in all very disappointed, he states many happy customers, I am not one of them. Richard J now has this blade to run an RC test and possibly find what kind of steel it is made from. But in a file test, it bites into the steel rather then skate over the edge. I expect that Richards test will show that it is in the 30's RC. What I got is a piece of s###. The seller stated that it would shave hair, made of 1095 and ? So far It WOULD not shave and would not hold an edge. I would not advise any one from wasting your money for one of these knives unless you are looking for a wall hanger, it does have nice file work.
