This accessory fits onto the Axminster Trade Honing Guide Assembly For Ultimate Edge (105281) and allows you to put a precise micro bevel ontop the blade using a bench stone.
Having ground the primary bevel on any tool the secondary bevel or micro bevel actually does the majority of the work. It is exactly what it says: it is a micro bevel which can be increased with ease each time the tool becomes dull.
The micro bevel guide is made of stainless steel and aluminium, and has the ability to accept the tool still mounted in the honing guide. The precise angle of the micro bevel can be easily set and with a few positive passes over a fine diamond or waterstone, a superb edge can be achieved. In fact it's probably the ultimate edge you can achieve with ease.
