The Free-Way saw is a quality tool, made and designed with attention to detail. The frame puts the correct amount of tension on the blade and the clamps will take standard coping saw blades. The spiral blades fitted in this coping saw work in the same way as a standard coping saw. However, the spiral-tooth saw blade allows you to make cuts in any direction without turning the saw. The case hardened saw blades are highly resistant to breakage and wear. Each saw comes with two spiral blades. The maximum cutting depth is 130 mm and the blade diameter 1 mm.
