I have a Chinook with the 440V blade. Great steel, super grind lines. Couldn't be happier...except one thing. I noticed a tiny little "dimple" or "crater" in the side of the blade. No more than .02 in diameter. From the appearance, its obvious that it was a bubble that formed when the steel was being formed. Its not mechanical damage. Not terribly deep, but, nonetheless quite noticable. Doesn't seem it would affect the overall integrity of the blade at all. But...I got to thinking...If this one showed up on the blade surface..are there others hiding in the steel below the surface? Just curious if others have noticed the same thing. Was there a bad batch of steel that came through or am I being overly concerned about nothing. To the Spyderco guys: Should I send this in and let you take a look at it? It doesn't REALLY bother me, just that nagging concern that it might be a problem with the whole piece of steel. Happy to send anyone a picture. Don't know how to attach it (or I'm not allowed to)

Maybe it's not a bubble but rather where Spyderco wanted to test the hardness of the blade. I don't know how many blades off the line get rockwell tested but if I understand correctly, that's what it would look like: a small imprint is left where the machine presses into it.
Just an idea...

Here is the picture sent to me by Sgt 127. It looks like its on the blade, is that what I see? If the mark were from testing wouldnt it be on the tang?
Yes I would wonder about that, I'm sure Papa Syder will come along and offer a suggestion or you could contact Spyderco warranty. Let us know what it turns out to be! Because of the edit REFRESS THIS PAGE TO SEE A DIFFERENT PHOTO!

Looks like an Rc test to me.

Hi Sgt. Sorry for your problem and concern. Steel imperfections do on occassion show up. You would have to send the piece to us for inspection. We do Rc some in each batch, but it looks like there are more than one from the photo, so Rc is suspect.
