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. It also converts the horizontal mounts to vertical, for easier access when sharpening knives edge trailing, and for guided honing using knife jigs (so-called Frontal Vertical Base or FVB).
