Check out the film and see how the jig works. SVA-170 supports the head of the axe without fixating it, so you can follow the shape of an individual edge, straight or curved.
The jig comprises a clamp with a rubber lined, wedge shaped stop, which holds the axe in a fixed position towards the grindstone. The clamp works on the Universal Support; on which it slides across the stone.
The jig is designed so that the rotation of the stone presses the axe firmly into the jig. You only need to hold and guide the axe with your hands. This jig only works with the stone running towards the edge. If necessary, the honing wheel can be removed to allow
clearance for the axe handle.

With the Tormek Axe Jig SVA-170 you will be surprised to see how sharp you can get an axe. The jig firmly supports the axe, and enable you to sharpen it with a constant edge angle.
The rotation of the stone presses the axe firmly into the jig and enhances the power from your hand, giving the edge a suitable grinding pressure onto the stone. You will not get any snags into the stone, which can easily occur if you grind free hand towards the grinding direction.
When using a high-speed dry grinder, it is easy to burn the edge and destroy the axe, with Tormek there is no such risk, the water continuously cools the edge.
Since the head of the axe is supported freely on the rubber lined stop you can follow the shape of the edge, straight or curved. A forestry hatchet has a curved edge while a carpenter’s axe can have an almost straight edge.
Choose the edge angle that is best suited for your type of axe. An all-round axe for sport and leisure has a larger edge angle than a carpenter’s axe. A splitting axe must have an even larger edge angle.
You can choose to sharpen the carpenter’s axe asymmetrically with a larger grinding bevel on the left side (if you are right-handed). The axe will then cut more easily since the cutting force is closer to the cutting direction.
