So I've loved the GB. Awesome knife ready for anything. I was out this past weekend whittling away... yeah, I was waiting for someone and bored. Anyway, today I looked at the blade and noticed there was a small chip towards the end of the blade.

Now red oak isn't that hard :) and I haven't used the knife since whittling. Is this common? Am I being picky?

Thanks-

I think it's around HRC 64-65 with good toughness @ that hardness.
 
No I don't think it's common or expected. But it's hard to draw a conclusion from a single chip. Have a photo? I suggest you keep using it and see if you get more odd edge damage.
 
I get small chips in my GB from doing woodwork with it.
Not too hard to sharpen out.
Someone correct me if I'm wrong, but I'm pretty sure that Mr. Bradley had a hardness of 62 for his competition choppers. Did Spydie up the hardness?
Spyderco does tend to make things a bit harder than some other brands.
My Spydies definitely chip easier than my other blades, nonetheless, the GB is the best work knife I've ever used.
 
I'm not sure of the hardness. Are you torquing the blade when cutting into wood? I'm surprised woodworking would chip the edge.
 
I did end up chipping the blade too on my GB after cutting through some 175+ data cables and 4-conductor cables. When I sharpened the chip out (keeping the factory set angle of course), I put it to work again on copper data cables and it has not chipped since. Could be that the toothy edge may ahve been caught and force exerted on that one small area caused the chip. Sharpen it out and have at it again.

I should have been more clear. I'm a bit tired at the moment... wasn't thinking.
There is contamination on the wood and yes I'm torquing it harder than is probably wise. I've hit a lot of metal with it, too.
I've worked this baby pretty hard and she's a champ!
A few little chips - tons of work.
Maybe he needs to sharpen away the factory edge a little. My edges seem more stable after a few sharpenings.
And thanks for the RC link.
 
My experience is the same. Even without sharpening away factory edge the steel is very good; once reprofiled to my taste it's beyond excellent.

GB has handled wood, copper wire, aluminium sheet and tent canvas, all without much edge loss (let alone damage)
