Get a flat bevel, or convert horizontal mounts to vertical The MB-102 Multi Base allows you to sharpen on the side of Tormek's diamond grinding wheels. This results in a completely flat bevel, which is preferable in certain applications. The MB-102 Multi Base is fully adjustable for optimal settings for each tool and jig.
