Anthony, I don't have the "trimmable" discs - just the regular ones with the fiberglass backing. 
Trev, I hear where you are coming from. I guess what I am NOT understanding is why the cloth backing strips don't just wear down and expose more new abrasive that is still sitting between the stacked layers of strips? The strips are 3/4" wide but the disc just stopped working after the 1/4" of strip that was exposed had worn out. So now it just rubs on the bare ends of the strips without cutting. Isn't the idea to have the entire strip wear away and not just the abrasive?
