I smell some statistical process control / 6 sigma nina-ry going on here

.
Are you talking about the blades that are broken during manufacturing, or is this total number of broke blades once they have been released to the "wild"?
Thanks man

.
I would guess, those released to the wilds. There is not very much test to destruction that goes on at Kabar, mostly, because of me.
I keed, I keed. Most new production knives that Kabar makes, are lab tested, then beta tested with guys like me, and others that get some first grabs, then, there are passarounds and so on.
The real testing starts when guys buy the knives. Real world testing is always the best, and I have to say, some of the most brutal. Not because of abuse, but simply p ut, guys that use their knives, use their knives. Over an extended period of time.
Lab test are short, brutal and to the point. You need to know how much lateral stress a knife can take, put it in the vice, grab the torque wrench, and pull until you get the snap/tink.
But some guy that uses a knife for 4 seasons duck hunting, cutting reeds, boat lines, game, cloth, rope, and so on, can tell you so much more about how well that knife is gonna do.
I've only had one issue with a hollow ground folder, it didn't like being batoned. At all.
Other than that, hollow grinds are OK in my book, but I prefer flat grinds over all.
