Interesting to see that he uses 440C as his steel and at what is considered a lower Rockwell than usual. Normal "optimized" Rockwell for 440C being 58, rather than the 55-57 he uses. My first handmade that I used on deer was 440C and I liked it; it was probably around the same hardness as he uses. I could completely do a deer with it(gutting, skinning, dis-jointing, butchering) before it needed to be sharpened. Takes a nice high polish that you can't get with 154CM/ATS-34. Nice looking blades.
