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).

Please note that sharpening on the side of the grinding wheel with the MB-102 Multi Base is recommended only with diamond grinding wheels. We don't recommend it for sharpening with grindstones as they wear down and require truing, which isn't possible on the side. 

The MB-102 Multi Base can be used with most Tormek jigs. It is designed to work best with these jigs:
KJ-45 Centering Knife Jig
KJ-140 Wide Centering Knife Jig
SVM-00 Small Knife Holder
SE-77 Square Edge Jig
SVS-38 Short Tool Jig
SVD-186 R Gouge Jig
