The present invention provides a blade sharpening device (10) designed for sharpening a blade (20) for a uniform sharpening of the edge (21) thereof. The blade sharpening device (10) contains a base (30) having a guide (60) slidably movable relative to the base (30). The guide (60) includes a material (63) that receives an impression of a blade (20) defining a blade contour. A blade holder (40) is attached to the base (30) for securing the blade (20) while being sharpened. A carriage (50) contains an elongated structure (56A, 56B) for interacting with the material (63) of the guide (60) which has received an impression of the blade (20) defining a blade contour. The guide (60) defines a sharpening path substantially aligning with the blade contour. The carriage (50) also has an abrasive surface (51) for sharpening the blade (20). In operation, the guide (60) and carriage (50) direct the movement of the abrasive surface (51) along the contour of the blade (20) for a uniform sharpening of the edge (21) thereof.

Le dispositif (10) pour affûter une lame contient une base (30) ayant un guide (60) déplaçable par coulissement par rapport à la base (30). Le guide (60) comporte un matériau (63) qui reçoit une impression d'une lame (20) définissant un contour de lame. Un porte-lame (40) est attaché à la base (30) de manière à fixer la lame (20) pendant son affûtage. Un chariot (50) contient une structure allongée (56A, 56B) assurant l'interaction avec le matériau (63) du guide (60) qui a reçu une impression de la lame (20) définissant un contour de lame. Le guide (60) définit un chemin d'affûtage s'alignant sensiblement avec le contour de la lame. Le chariot (50) a également une surface abrasive (51) permettant d'affûter la lame (20). Pendant le fonctionnement, le guide (60) et le chariot (50) dirigent le mouvement de la surface abrasive (51) le long du contour de la lame (20) pour effectuer un affûtage uniforme du bord (21) de la lame.
