I have an oregon one with the snaps that hold the file on but it SUCKS and I want one that you have to screw the clamps tight.
Agreed. Those clamp style flex. You want the Stihl brand. It will be labeled 13/64" but 7/32" works fine in it.
The husky file guide works very well and can be had on amazon for bout $13..and comes with a coupla files..7/32"..just fyi
