I wanted to ask you guys about stag retaining dirt. I work with trucks and truck parts in a dealership and I never want to carry my stag knives here because I don't want to ruin them. Does anyone have any experience with wrenching on cars, farm machinery, or any other greasy stuff and carrying a stag knife? I'm worried about brake dust and fluids that might be on my hands when I grab my blade. It might not be worth it to bring it, but I really love stag and I'd like to throw the couple I have in the rotation a little more...
