I have a satin INFI SS4. INFI is just as stain resistant as stainless but for a different reason. Mine also has a wicked zero edge. It was a fave for a ong time but has not got a lot of use since I got the Swarden and Mule.
That wet enviro looks fantastic Vic! I love the shiny black handle and the swedge really gives it some attitude. 440C is one of those great steels that gets neglected.
Well, of course we would all love INFI at SYKCo prices! If the heat treat is right, 440C is a great stainless knife steel, as is the 12C27 that Bark River uses. I have three or four knives in the 12C27 and it is as good or better than 440C as far as I can tell.
