Amazing new tool i reinvented the file

[Buster Gonad]

Thats a great design, congrats. I too have reinvented many tools to do a better job. Well before I knew of this Forum. I'm especially interested in you r inner assembly that keeps the inner tension of the belt.
...Any diagrams of the inner flip over lever. I'm not a plagiarist...just a Toolmaker that appreciated the effort relative to the result gained. Good Onya Mate.
