After seeing those CARTA test results for wear resistance recently, I am perfectly happy with 3V. Actually more than happy, that stuff is downright amazing.
Something that I'm looking for, but probably would never find anywhere else is a nice light 11" bowie. Sure, others may make a "bowie", but they would probably weigh a ton more than a dedicated fighting knife should. 1/4" thick with either a distal taper full flat grind, or better yet a distal taper full height hollow grind. *drools*
Give it a skeletonized full tang K9 rendition of the coffin handle and you're set.
I'm actually just looking for a big knife that cuts ridiculously well, but the only reasons for a knife to be longer than 10" are either to chop or to fight, and I already have a bunch of choppers.
