Backsaw for cutting fret slots. This is a “Rosewood-like” handled, fine toothed backsaw (20 teeth per inch) with fully set teeth. It quickly cuts through Ebony or Rosewood, leaving a clean and precise slot. It has a .023” (.55mm) kerf for normal fretwire sizes and the steel is hard enough to cut nonferrous metals. These saws are custom made for us with the blade reversed to cut in the “pull” direction. This is for more accuracy and ease of cut. (This is the saw that comes with our fretting system, SPFSYA.) If you use it as a fret saw only, it has an extra long life. Depth of cut 1 5/8”.
