So, I've been snatching up a lot of Spydercos lately, and the Lum Chinese folder is among my favorite patterns from any maker. My newest one, a black G10 XL model, just arrived, purchased brand new. Everything is great, blade is centered, locks up snug, except the steel has a big ugly stain along the bottom. You can see it in the following pics (first pic is how it looks in regular lighting, although it looks a little lighter if you hold it just right, as in the second pic):

I've already taken a cloth and rubbed oil over it to see of it's a surface stain, but it doesn't seem to be, and it won't come off. Anyone know what this is and how I can get rid of it? Is it a flaw in the steel and/or does it lessen the quality of the blade in any structural/functional way? Or is this something I should send back to Spyderco as a warranty issue (or perhaps to the seller, forum member National Knives)?

Thanks for any help!

Yeah, I'm going to pick some up locally if I can find it. Will it scratch up the finish or is this kind of stuff abrasive free?

I've used Mother Aluminum Polish, and it took some scratches out of a ZDP Endura. Go slow and start with a little at a time. It will clean up the blemish. I also had one of the Emerson Rescue Enduras with the exact same staining/blemish, the polish worked really well. I ended up cleaning the entire blade, the end result was that the knife glided through material and looked perfect. Just remember to wash it afterward if you use it on food.

Awesome. I'll give it a shot this weekend. Blemishes like this don't indicate some structural flaw (and therefore cause reliability or performance issues) in the steel, though, do they? And polishing with a paste shouldn't ruin the blade's factory finish or void any warranties, would it? Sorry for the noob questions, but, well, I'm a noob :)
 
I'm not sure what causes that staining to be honest with you. As far as being a structural flaw, I don't think it would be as it is on much of the blade. It could be from the hear, or some sort of corrosion developing, your guess is as good as mine. As I mentione, go slowly with theolish, do not apply too much pressure in one specific area, just give the whole blade a once over and check the results. Apply more paste as you see fit, looking forward to seeing how it turns out.
