The Indusrial Pro Blade has three replaceable tungsten teeth. It is precision machined from hardened tool steel and cuts wood with a remarkably smooth and controllable cutting action. The Pro Blade teeth can be unlocked and rotated to expose a clean cutting surface. Pop recommends you rotate the teeth every two or three hours to prevent their self-tightening design to be come too difficult to remove. Blade comes with a Torx wrench.
This is an excellent sharpener for Arbortech's Tungsten Teeth Blades, Shaping Ceramic Sticks, etc. It is not just for your woodcarving tools but for your kitchen knives and scissors also. Keep one in your tool box and fishing kit too!
When sharpening the Tungsten Teeth simply use in a filing motion straight across the teeth. The teeth are hollow-ground and after repeated sharpenings will loose their fine edge. This will be evident in the smoothness of your cuts and the teeth should be replaced.
For the average hobbyist, the teeth should last you a few years at least.
