Hello from GeetarGizmos.  We are happy to offer two of our biggest selling fret dressing tools in a single handy set.  Our Thermo-Formed Fret Stick and our Smooth Finish Triangular File.

Our Thermo-Formed Sanding Stick is a new development in fret profiling and crowning - the specially shaped tip is achieved by a heat process we've developed in our shop.  You've probably seen the concave tip steel files that sell for around $50...  Our Sanding Stick offers a similar result at a much lower cost. As you press the tip downward onto the fret, you force the sandpaper belt to conform to the Thermo-Formed tip cavity. This thereby produces a perfectly shaped fret profile. All you do is sand normally with reasonable downward pressure.

With the Sanding Stick you receive two sanding belts each of 180 and 400 grit. The belt is easily installed by compressing the Stick's internal spring and slipping the belt over the top.

Secondly, our Triangular Fret File is a smooth grit type measuring 5"long by 3/16" max width.  Being triangular, it gives you three working surfaces.  And we smooth and round each of the three corners to eliminate any possibility of fingerboard damage while you work.  Great for fret leveling and shaping. Removes material quickly and cleanly.
