Ok then. Lets assume for a second that I dont have 25years experience in the bush. Or lets also assume that all of the mesquite I processed successfully and without issue during that time with other knives, including cheap machetes, was just dumb luck. Should the metal bend? This is an honest question, not being sarcastic.I can't say that I am surprised with the results you found from chopping mesquite wood, if it is anything like the mesquite I have encountered.
When I lived in Hawaii, I had similar experiences with Kiawe wood, a naturalized species of mesquite.
It ate machetes, blunted axe heads, and curled back the teeth of saws. I never found anything that would stand up against it without some damage or major dulling.
I just stuck with a saw, and it became a beater really fast.
