I own a Case peanut chestnut CV. I noticed that when I open the main clip blade, on the side opposite the thumbnail notch and near the point, there seems to be some rubbing marks. Without posting any pictures, I can tell you that the knife came with both blades perfectly centered and are still perfectly centered, plus there is no blade play in either direction. Is it normal to have some rubbing marks near the tip, maybe when I'm opening the knife with my thumbnail, the blade rubs against the inner bolster lining when opened??
