Every so often you'll see someone compalin about a knife and say "the tip of the blade broke while I was...."

The question that always sort of bounces around in my mind is "How can the tip of the blade breaking off ever be the knife's fault?"

Wouldn't it almost always be from improper use?
 
Steels have hardening flaws, some are poorly designed, others are promoted for uses they are not actually designed to handle.

It's the old edge holding vs ductility conundrum. You can't really have both, yet.

People can break sharpened prybars. There's one in the tool box at the other press brake at work. I've broken tips off pocket knives prying fuses out of autos, or stabbing wooden boards and bending them out sideways. I'm always disappointed in my abuse, not the blade.
 
I've had more than one knife break of the tip [less than 1/8"] without abuse . I attribute it to improper heat treating or overheating during grinding.
 
Yes, my fault, my name is Luis and I am a knife tip breaker... I recently broke the tip of the sheepsfoot in my old Schrade 98OT, I reshaped it making a small belly and it's a working knife again, but it's not the same, @&%#*.

I had a Case pocket knife blade point break once cutting pine. Case replaced it without a question. If I am mishandling a knife (prybar etc.), then it's my fault and not the knife's. My wife is famous for using fairly good kitchen knives (steak knives, etc.) to pry things and she breaks the tips. I won't say how I feel about that activity.
