A 45-degree chamfer can be made on a 90-degree convex angle, and the width can be freely determined (up to 25 mm) simply by adjusting the screw.
Since chamfering is performed by overuse the same part of the cutting edge, the durability and abrasion resistance strength of HSS steel can be demonstrated.
No blade maintenance required.
