Ideal and incredibly handy for getting into confined areas, this set of mini saw frames handles a variety of detail tasks. Not intended for general sawing applications, each frame in the set provides precise control of the saw blade for delicate operations such as preparing mountings for stone-setting, working around prongs, adding fine touches to wax carvings or scrolls. 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; frames are not adjustable. Keep one on your bench, one by your laser welder, one in your traveling tool box! Or, use a different size or style blade in each frame--the color-coding makes it easy to pick up the style you want at a glance. Frames hold standard jeweler's saw blades.
