I bought one of these gizmos from a stihl dealer.
This thing is the cat's meow.
Sharpeners teeth while at the same time cuts drags if too long to ideal length.
A no brainer to sharpening.
No guess work on drag tooth length.
Here is a you tube showing one of these things in action.
I paid $40 for mine,,comes with square file and 2 round files already installed.
Been cutting wood, and detecting, and yes deer hunting.
So real busy.
Cheers
