I seen a guy hack through a deers pelvic bone and destroy a SAR 6’s edge. It looked like a serrated knife from Spyderco after. Lol. I sent it in to the shop for him and they re ground it it out. Came back like new but a tad thinner height wise to get it all out. he said he didn’t trust it and sold it. He is not a knife guy like all us and only bought it cuz I told him about Busse and hyped them up so much so he bought it off me. I felt bad as I know bone is hard on edges but I’ve also done that one time on a deer but with a gen 1 SR-101 SWAMP RAT Howling Rat and was still razor sharp. No damage at all. But the SAR 6 was much thinner type grind from factory compared to most of there knives. I’ve never hurt any of my INFI or SR-101. Yes I’ve had tiny tiny chips but sharpened them out by hand. That knife of his was way to much for that. It needed a belt sander to fix.
