StewMac Fret End Dressing File The first thing a player feels is the fret ends, so always shape them with this professional quality luthiers fret end dressing file. Smooth, non-marring edges glide on the fingerboard while the fine-toothed sides deburr and round the fret. For rounding, shaping and deburring. This specialized file dresses the ends of the frets after they've been installed, trimmed flush and beveled. One thin edge is ground "safe" to help protect the fretboard, and the other rounded over. This file cuts only where it needs to: on both sharp corners of the unground thin edge, and on both of the wider toothed cutting surfaces. The cutting surfaces smooth the fret end bevel, and the sharp corners nip off the sharp burrs at the edge of the fret bevel where it meets the edge of the neck. With the safe edge facing down, the cutting surfaces of this little file do a good job of rounding over and shaping the fret ends. File dimensions: .062" x .125" x 6", with 3" cutting surfaces.Fix Sharp Fret Ends Safely - The Stewmac Fret End Dressing File's Smooth, Non-marring Edges Glide On The Fingerboard While The Fine-toothed Sides Deburr And Round The Fret.Improve Playability - Removes Snags And Burrs From Rough Frets Or Fret Sprout To Make The Neck Feel Smooth For Great Playability With Our Battle Tested Fret File.For Rounding, Shaping, And Deburring - This Specialized File Dresses The Ends Of The Frets After They've Been Installed, Trimmed Flush, And Beveled.Built To Last A Lifetime - Our Promise To You Is Simple, If Any Of Our Products Ever Wear Out, Break, Or Fail To Meet Your Every Expectation, Simply Return It For A Replacement.Fret End Dressing File Dimensions - .062" X .125" X 6", With 3" Cutting Surfaces
