Cheers for the input there on steel Ash - are there no "stainless" steels worth using?
yes there are, falkniven are stainless and tough. but i find my cpm 3v knife almost impossible to get rusty. its dosnt even turn purple when cutting oak and sweet chestnut.
in my opinion stainless steels arent tough enough for a knife the size you are talking about, and the next compromise is A2 and cpm 3v if your looking to have some stain resistance and still be tough. falkniven get around this by laminating. I am not sure if you can soft draw the spine of stainless blades for toughness, thats way out of my league
and to the best of my knowlege it cant be done easily.
i havent any personal experience with A2 but it has about the same chromium content as cpm3v so should be roughly as stain resistant, but this may not be the case. it will be more so than 01 though.
