New frets won't seat correctly until the old fret slots are clean! Designed by fretting expert Dan Erlewine, each of these unique saws has two 3/8" blades. One cuts on the pull stroke, the other on the push. The three saws have different blade thicknesses; use them in sequence as needed to loosen packed wood dust and old glue, or to deepen shallow fret slots, even on bound fingerboards. They're better for these tasks than a standard fret saw, which won't work on a bound board and can unnecessarily widen the slots on a radiused board.
Each saw is 9-3/4" overall, with a wooden handle and two 3/8" blades.
