The invention provides a novel cutting tool used in wood working, which has a sufficiently thick cutting edge allowing stable cutting of a veneer from a log as well as an apparatus for and a method of grinding the cutting edge to have a favorable shape and a relatively large angle. The apparatus of the invention includes a table which an elongated cutting tool extending along a longitudinal axis of the table is mounted on, a fixing element for pressing the cutting tool upright against an upright plate, and a carriage which is reciprocatingly movable along the longitudinal axis of the table. The carriage is provided with a pair of grinding wheels which are respectively movable into and out of endwise grinding contact with an upper surface and a lower surface of the cutting edge of the upright cutting tool at desirable angles. The apparatus further includes a control mechanism for controlling a moving distance and an inclined angle of each grinding wheel according to a preset number of grinding steps and a predetermined grinding depth and a predetermined grinding angle at each grinding step for each surface of the cutting edge. The upper surface and the lower surface of the cutting edge are respectively multiple-taper ground to have an arc-shaped surface from the tip portion to the base portion of the cutting edge.
