>>319378>A friend's got a knife made with D2 that he uses for everything I wouldn't use a knife for and it does reasonably wellas long as that doesn't involve holding a good edge and actually being stainless then, great. even properly heat-treated 420HC would exceed its performance in prying, stain resistance, and high level edge holding.
the middle of your post seemed to focus around:
>making knives in a homemade forge >using partial height primary grindsI have issues with both of those things so lets stay away from them for the sake of staying civil.
>What do you think about the 440 and AUS steels?I think 440A is awesome if properly heat-treated. it is tough and holds a fine edge. I think 440C is utter shit and hold just a slightly better opinion of it than D2 as, 440C is at least stain resistant.
I'll just sum up my feelings on knife steels:
I think most carbon steels have no advantage over stainless in knives. I think stainless knives should stay as close as possible to the carbon saturation line in this graph (i.e. AEB-L and even 420HC). I think steels used in disposable razor blades are about as good as it gets for knife steel. everything else is just bullshit marketing and hype. seriously, what is better than those little disposable rectangle blades used in warehouse box cutters and scraping gaskets? it holds a super fine edge and is tough as shit for as thin as it is. a knife made out of it would be killer. if anyone thinks cost is the reason they don't use S30V in razor blades, they are delusional.
