Hey guys i was just doing some whittling with my benchmade subrosa in s30v and when i looked at the blade i noticed it hade several chips!!
i was carving a knife handle already on the knife so i figured i must have hit metal or something but i know that it couldnt have been more than a tap. i was curious about how weak this metal is so than i took out a screw driver lightely tapped the edge against it, and low and behold the edge had badly dented. should s30v be this weak?
 
^As he said

Also, you say "chip" in the title yet "dent" in the description. Which actually occurred?

And finally, is it factory edge? If not, what did you put on for the edge angle?
 
Sorry i cant seem to figure out how to post pictures and it both dented and chipped also factory i did not sharpen it.
 
Take it back to where you bought it from. The edge may have been ground too thinly or it may have had a bad heat treat (it is supposedly very difficult to heat treat properly), or possibly both.

Sometimes when whittling, it is possible to chip the edges if you accidentally flex the blade while you make the cut.

Pictures would help.

It could be a bad heat treat. I'd send it back to BM and let them evaluate and resharpen/replace it.

I had a Gerber Freeman in S30V 'dent' on it's narrow angled edge. It took a while with my 30 degree settings and Sharpmaker, the key being to clean the files as you use them (Bon Ami), but I got the profile where it should be - then touched the edge up with the 40 degree setting. It's held up fairly well ever since then, although it isn't as hard/long wearing as Buck or BM S30V. It could just be the final grinding of the original edge 'drew the temper' - and my slower (Less heat build up!) reshaping found 'good metal'. My BM's in S30V are nearly as good as my Bucks in S30V. I 'tried' the Gerber Freeman in S30V and stag scales because it was made in the USA, as other 'Freeman' models weren't. Good luck!

PS Quit whacking knife blades against a screwdriver shank!
 
Considering that my Benchmades generally have lower hardness compared to the same blades from other companies, it's strange that the blade chipped. The only explanation I can think of is that the sharpening process made the very tip of the edge brittle. It's not uncommon for the "good" steel to expose itself until after a few sharpening sessions.

And as for the dent, you hit a very thin sliver of steel with a thick chunk of steel. Even a minor tap would concentrate the force into the tiniest bit of contact surface. :) Not really surprising if you think about it.
