I have a few fixed blades in S30V, the Al Mar SERE Operator, Chris Reeve Green Beret, and the Ritter Survival. They are good knives, and I really put the GB through some beating and abuse, but for toughness I'd choose any of the Busse-made steels or one of the Rangers in 5160 over my S30V blades. If Scrappers, Swamp Rats, and Busses weren't tougher than ordinary knives, none of us would even be here on this forum.
