Erick Coleman: Strings need to move freely through nuts and saddles, so the slots need to be as smooth as possible. Files are for shaping and lowering string slots, but they do leave tool marks. An abrasive cord smooths out those marks. Mitchell's Abrasive Cord is perfect for getting into tight places. A couple light back and forth strokes removes any marks from my slotting file, leaving a smooth surface for the string to ride on. Use it to smooth out nut slots and string slots on acoustic bridges.
Sometimes bridge plates can develop grooves and burs that can chew through strings. Use the abrasive cord to smooth out these grooves, giving the string a smooth surface to ride over. I use it for reefing work to remove finish from tight spots. Save your scraps because a little goes a long way. For most jobs, you can reuse it again and again. It comes in four sizes. I've been working off the same rolls for years now, and I use this stuff all the time.
