Out of curiosity how does the 420HC of the Buck compare to the Krupp 4116?
Like many steels, how 420HC depends hugely on the heat treat it gets from the knife maker. Buck does an excellent job with 420HC.
I can't tell the difference between Buck's 420HC and Opinel's Sandvick 12C27 or really good 1095. They are fine carbide steels, take a keen edge, are reasonably tough but won't have the abrasion resistance of course carbide steels. But then, they sharpen up very easily on crude stones.
I think the big issue with knives like the Bucklite Max is the difference in the grind. I find hollow grinds like on the Bucks to be good cutters (of rope or meat) but horrible slicers (cardboard, potatoes). In particular, expect the Bucklite Max to bind more when batoning wood. This has to do with the grind, not the steel.
Buck makes a great knife. I wish they offered more knives with a flat or convex grind.
I think the Bucklite Max is a screaming deal.
