benchmade mpr with m390 steel knife. Is it better than d2 s30v or 154cm steel?
well first of all u hav 2 get a mpR490 STEEL STOOLMADE
From what I understand m390 is a new steel (at least for benchmade) so there doesn't seem to be a consensus on how it performs. Looking at the table, it should be very corrosion resistant. I'd guess it could be classified as a stainless steel. Sorry I don't have more info for you. EDIT: here's a link from the steel manufacturer. I hope this info helps.
From what I read M390 is relatively wear resistant, with very high stain resistance and good toughness. It is quite hard to qualify steel as better than other steel because it depends on many factors. E.g. for a small folder designed for delicate cutting D2 at high hardness would perform better, but if the environment is corrosive, like saltwater then M390 would be better. I'm not so sure about using stainless steels in large chopping style knives, but I've seen M390 used for them as well. Obviously hardness had to be lowered, which reduces edge holding ability, especially at low angles. Overall, it's a good steel, but if it will outperform S30V or D2 or 154Cm depends on heat treatment and blade geometry, knife designed use, etc.
