The MB-102 multi-holder allows you to sharpen on the side of Tormek diamond grinding wheels. This results in a completely flat grinding bevel, which is preferable for certain applications. The MB-102 Multi Holder is fully adjustable to allow optimal adjustment for each tool and fixture. This allows you to convert the horizontal holder into a vertical one. This facilitates access when sharpening with the rotation of the wheel and for guided honing with knife devices.
