ABSTRACT:
An apparatus and method for sharpening a cutting tool, including the grinding and honing of the cutting tool is described and illustrated. The apparatus comprises a base plate with a biasing frame mounted on the base plate. A tool holder is clamped to the biasing frame and releasably clamps a cutting tool, having an edge which is to be sharpened. A variety of tool holders allow the sharpening of different types of cutting tools. The cutting tool, and particularly, the edge thereof, is held in a stationary position and an abrasive member is moved with respect to the cutting edge of the tool. The apparatus forces the cutting edge of the tool against the abrasive member with a uniform amount of pressure and at a selected angle. Both the pressure and the selected angle are easily adjustable by the user. When the major variables, such as angle of sharpening and the pressure between the abrasive element and tool are fixed, an accurate, correct and reproducible sharpening will occur. A precise sharpening of the tool will automatically result since only the abrasive stone is moved back and forth across the base plate under the cutting edge of the tool.
