New style Archone made in Japan by Naniwa. Ideal for creating ridelines on curved shears. Size 133 mm X 28 mm X 20 mm Material is Gouken high quality Japanese waterstone.
Note: two sides are flat, one side has a convex curve and the other a concave curve.
The Archone is a simple Japanese waterstone cut arcs for creating ridelines in shears that would be impossible to hone using a traditional waterstone. While it is not as perfect as a waterstone it gives the closest approximation to a flat rideline without ramping or relaxing the edge. It is quick to use in fast paced situations like hair and pet shows where there is not time to take the shears apart.
The key is electrical tape wrapped around the center. This allows the rideline to be closer to flat.
