The only one I recognize for knife steel is 440C, but its listed as pretty thick. Stainless 303 and 416 can be used to bolsters, liners, guards, etc.

Doug Lester 01-26-2012 06:12 PM

I would say that none of them that are in the thicknesses that you would use for stock removal will make an adequate knife blade. As Cpt-Jens pointed out 440C will make a good blade but the size available is too thick and forging it is challenging. Deffinantly not for the beginning smith. If he were my friend I would have to tell him that there is nothing that he has access to that would be useful to me for making a knife.

Ditto. A good bit of that stuff isn't steel at all such as Delrin (a kind of nylon), titanium, and inconel. Ask him if he can get the 440C in .250 or less thickness. Or, if he's at a machine shop, ask him to split one of those 440C bars lengthwise so that it is half thickness (a waterjet or EDM could do this).....

Eli Jensen 01-26-2012 08:05 PM

Or, you could take the 440C as it is and make a knife like this?

Good one, Ely!! Actually, that looks a lot like what most of us envision making as our first knife....

Thanks, he does in fact work at a machine shop making high performance springs for aircraft and other vehicles, so I will ask if he can cut down the 440C like you said. Thanks everyone for the advice!

Check the date on those posts - 2012. 9 years ago.
