Hello,
Sorry if this is the wrong forum, Im new here.
I bought a few Spyderco Byrds and they arrived with some weird sticker on them which I spent few hours to remove (wish soap and water). But after removing the stickers, I saw on of one of the knives, that there is a stain which cant be washed away anyhow. What is it, should I return it for a new one? :/
