Some people break blades, but I never have had that problem.
I've seen a bunch of comments on Rokslide/etc about needing a stout knife in order to work through joints, or that replaceable scalpel blades break all the time. There was even a comment recently about how good a Benchmade knife is because the user didn't "chip it" while butchering, like that is a normal thing to happen with other hunting knives.

I thought similarly, until I butchered a moose with an ortho surgeon. That surgeon could not be bothered with a regular hunting knife, instead breezed through all the joints in the moose with a Havalon like it might wake up from anesthesia if the operation took too long! So fast, so smooth, zero torque on the blade.
I learned so much that night.
The surgeon said something to the effect of, "If I can take apart and put back together human hips and knees all day with a scalpel, quickly chopping up an animal is easy. I don't even need to worry about putting the ligaments back together."
I'm still many years of med school behind that doc, but since then I've gotten a lot better about *never* torquing my blade on anything, *never* running the cutting edge on bone, *never* digging the tip into a joint in a blind effort to pop it. It all goes so much faster when the joints are disassembled with no force beyond an index finger pressure on the cutting edge.
