Don't panick just yet! I bet if you look reeaaaallll close at your SOCOM blade, you'll find that what you see is Aluminium rubbed off on the Black Ti coated surface. The Titanium coating used on Microtec's blades is very similar to ours[EDI KNIVES] and is MUCH harder[about 90 Rc] than the Aluminium foil. What you are probally seeing is silver looking Aluminium rubbed off on your black blade. I could be wrong, but thats what has happened on some of our blades. A little elbow grease with a cloth usully takes it right off. Be careful, don't use anything too abrasive[no scotchbrite pads]. If in doubt, please call Tony @ MicroTec, I'm sure that they'll help out. Hope this helps.
