The Tormek Square Edge Jig replaces the chisel and plane iron jig. Tormek re-designed it to reference the back of your plane iron or chisel - insuring a square grind on the cutting edge. A unique mounting clamp - which holds even tapered chisels - avoids skewing the chisels edge when securing the tool in the jig. A new safety stop secures to the tool rest support bar to prevenet the tool from slipping of the edge of the sharpening stone. The jig works with all previous Tormek machines and is included with the T-7 and T-3 Sharpening Systems.
