I'm not sure it is unappealing, for me anyway, if someone wanted a knife made from it I
would time permitting no hesitations.
The problem I see with it, is the price you could have one of the high end stainless steels like s30v, s35vn, Elmax, etc. So most knife makers are going to make a knife that performs so similar most people couldn't tell the difference, but will not stain or rust. IMOP that's probably the deal, but don't really know.
