The device includes a holder for retaining the knife blade in a fixed position with the cutting edge accessible from above. One end of a moveable abrasive part is situated above the cutting edge. The other end of the abrasive part is supported by a retaining member and sets the angle of the abrasive part relative to the knife blade when the abrasive surface contacts the cutting edge. The cutting edge is sharpened as the abrasive part in contact with the cutting edge is moved along the length of the knife blade. The abrasive part may be a stone or a rod with an abrasive surface. The retaining part may have a ring shape or take the form of a clamp which attaches to the stone in different positions.

An apparatus for adjusting a knife edge offset in a cutter toolhead having a cutter toolhead frame. The apparatus including a knife moveably coupled to the toolhead, an actuated arm moveably attached to the cutter toolhead frame, a computer controller for controlling the movement of the knife and actuated arm, an abrasive sharpener moveably attached to the actuated arm and adapted to contact the knife, and a sensor adapted to determine a distance between the cutter toolhead frame and the actuated arm. The computer controller of the apparatus is further capable of adjusting the movement of the knife and the actuated arm as a function of the distance determined by the sensor.

A knife block may include a block body with a recessed portion and a block insert positioned at least partially within the recessed portion. The block insert may include a first knife slot and a second knife slot. The knife block may include a first knife sharpener coupled to the block insert, where the first knife slot is sized such that a first knife is sharpened by the first knife sharpener each time the first knife is removed from the first knife slot, and a second knife sharpener coupled to the block insert, where the second knife slot is sized such that a second knife is sharpened by the second knife sharpener each time the second knife is removed from the second knife slot. The knife block may include a first knife storage slot and a second knife storage slot.
