Ideal and incredibly handy for getting into confined areas, this mini saw frame handles a variety of detail tasks. Not intended for general sawing applications, this frame provides precise control of the saw blade for delicate operations. The compact size and light weight ensure close control; the 2-3/4" opening will hold any blade, even broken blades, trimmed to that length, and sandpaper. Frames are not adjustable. Frames hold standard jeweler's saw blades.
