I've been using StewMac's straight diamond crowning file for probably two years now, and it's been great. It's still cutting well enough, though perhaps not as quickly lately. I know regular files will wear with time and use, though this is my first experience with a quality diamond file. Not sure if it's in my mind or not, so I figured I'd see what kind of mileage the rest of the tech crew is getting. Thoughts?
