Title
(EN) KNIFE BLADE SHARPENING DEVICE AND METHOD
(FR) PROCÉDÉ ET DISPOSITIF D'AFFÛTAGE DE LAME DE COUTEAU
Abstract
(EN)
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.
(FR)
Le dispositif selon l'invention comprend un support pour retenir la lame de couteau dans une position fixe avec le tranchant accessible depuis le dessus. Une extrémité d'une partie abrasive mobile est située au-dessus du tranchant. L'autre extrémité de la partie abrasive est supportée par un élément de retenue et définit l'angle de la partie abrasive par rapport à la lame de couteau lorsque la surface abrasive entre en contact avec le tranchant. Le tranchant est affûté lorsque la partie abrasive en contact avec le tranchant est déplacée dans le sens de la longueur de la lame de couteau. La partie abrasive peut être une pierre ou une tige présentant une surface abrasive. La partie de retenue peut avoir une forme annulaire ou prendre la forme d'une pince qui se fixe à la pierre dans différentes positions.
