The reality is that in a large, thick fixed blade designed for heavy use it would be almost impossible for the operator to tell a difference between 420HC and ATS or S30V. Actually the S30V will have more chance of chipping on hard targets. Now, on a thinner blade designed for fine cutting, like a skinner, the superior edge retention of higher end steels becomes more noticeable.
The bottom line is the heat treat, and we are lucky to have the best in the world. Our 420HC heat treated by Paul Bos rockwells at 58+ and out performs many competitors ATS-34 products. The added corrosion resistance is nice as well.
I am planning a run of these knives in higher end steels for those who prefer, but they will cost more.
Thanks,
