Abstract

Traditionnellement, étant donné que la partie arête présente une coupe en forme de coin faisant saillie sur les côtés opposés et qu'un couteau de cuisine est utilisé dans un état émoussé, un oignon est coupé tout en étant écrasé au moment du hachage de sorte qu'une odeur irritante est pulvérisée et cause de ce fait une douleur au niveau des yeux. De plus, lors du processus final de déchiquetage, l'oignon est coupé tout en étant écrasé parce que le mouvement haut/bas du couteau de cuisine est répété provoquant ainsi une odeur irritante encore pire. Un couteau manuel comporte un corps de couteau plat et mince (1), une partie arête continue en zigzag (2) formée dans le corps de couteau (1) à angle aigu, des arêtes pointues tranchantes (2a) formées au niveau de la partie faisant saillie de la partie arête (2), et des arêtes de tranchage (2b) formées de manière symétrique allant des arêtes pointues (2a) vers les parties évidées, un côté mis en œuvre avec la partie arête (2) ayant une forme courbe faisant saillie sur 0,2 à 1,5 mm, des parties anti-casse (3) étant mises en œuvre sur les côtés opposés de la partie arête (2), le corps de couteau (1) étant remplaçable et une partie de préhension (4) ayant une forme courbe.
