The Multi-Sharp ATT3001 ‘Wetstone’ Chisel & Plane Blade Sharpener has the following features: *WATER-COOLED SHARPENING Water-cooling is acknowledged by professionals to hone the finest edges. The ‘ Wetstone’ uses re-circulating water to eliminate over-heating of the blade edge and loss of steel temper –‘blueing’. Simply fill the built-in reservoir with water, turn on the power drill and a continuous film of water covers the face of the grinding wheel. *WOOD CHISELS / PLANE BLADES ‘Wetstone’ sharpens even badly damaged chisels / plane blades quickly, because it uses the relatively high power / torque of an electric drill. The chisel clamp accurately holds the blade at the selected angle for a precision ground edge. *Blade capacity: 10-60mm. *Sharpening angles: 25,30,35,40 for primary and secondary bevels, plus firmer, bevel-edge and rebate chisels. *The traditional leather strop removes any burr, for a razor sharp edge. *SMALL TOOLS The Tool Rest gives a firm base for re-pointing and re-edging a whole range of small tools including: cold chisels, bradawls, screwdrivers, centre-punches, scribers, wood carving / turning tools, gouges etc. Marked angles on the rest indicates the tip angle. *Power source : any electric drill.
