I get why they do coated on stainless, people like the looks of it, someone might want a fully blacked out knife etc. Personally its not my favorite, it does add to the look on some knives but once you use them enough it ruins the look anyways as cerakote is garbage compared to DLC and just look horrible when its worn off. I can see if its a tool steel but some models only offer stainless. I have a bunch of knives with DLC and a few cerakote, either because thats all they offered in that model or with some of my other ones like spyderco exclusives it was all I could get my hands on as the satin were gone (still looking on the secondary for one in particular to either buy or trade for the coated)
I also do like that PSK quite a bit compared to all the other new stuff they released which just seems boring, but the price is a no go for me, they treat it like the next s90v where they think the steel is worth another $100 more (s90v isnt worth that much more either but the raw steel is more costly than magnacut or at least was)
