Abstract

La présente invention concerne une lame pour trancher des aliments sous forme de barres, qui présente une face avant opposée à l'aliment sous forme de barre et une face arrière tournée vers l'aliment sous forme de barre, de même qu'au moins une zone de montage qui relie la lame à un mécanisme d'entraînement rotatif, ainsi qu'un tranchant au niveau duquel la face avant et la face arrière convergent selon un angle d'attaque aigu et une surface d'angle de coupe au niveau de la face avant qui jouxte le tranchant. L'invention concerne en outre un procédé d'affûtage d'une lame.
