The SVA170 is for carving and carpenter's axes. The head of the axe is supported freely on the rubber lined stop so you can follow the shape of an individual edge, whether 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 need only 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.
