    Sal, or anyone who knows for sure, is it true that Spyderco is lowering/has lowered the Rc hardness of their 440V blades down to like, 55-56 Rc? Isn't that a bit on the soft side, I understand ppl were complaining about chipping and such, but one of the greatest things that I liked about my Military (which I sold unfortunately) was its awesome cutting power. Besides, it never chipped on me (except for the time I dropped it on cement, that doesn't count I think [​IMG] )

    The hardness has been lowered as you noted. You can do a search for the specifics.

    Jadis - testing indicated that the softer Rockwell on CPM-440V cut better and longer than the harder steel. We believe the "chipping" was more the rsult of our very thin factory edges, rather than Rockwell.

    "Harder" is not always better. Glass is very hard, water is soft, and yet water is used to cut glass. Try to keep an open mind as modern technology changes old beliefs.

    A nice restating of an oft used analogy from an ancient religion, Master Sal [​IMG]
