Laborsaving back-abrasion-preventive chopping knife

Abstract

A traditional chopping knife has a front cutting blade and a rear back, there is a great space between acting force applied by a hand to the knife and reactive force applied by food material to the cutting blade during chopping, the hand holding the knife may spontaneously move to the hard and narrow back, and the rear middle of the thumb of the hand may be hardened by the back; a laborsaving back-abrasion-preventive chopping knife provided herein comprises a cutting blade, a handle and a back, a groove allowing insertion of fingers is provided between the cutting blade and the back, the handle for a hand to hold on is formed by the upper edge of the groove and the back, a structure with the cutting blade below the handle is formed, a plumb symmetric center line of the handle and that of the cutting blade are collinear, and therefore, the acting force applied by a hand to the knife is collinear to the reactive force applied by food material to the cutting blade during chopping. The laborsaving back-abrasion-preventive chopping knife is laborsaving and free of abrading hands; as the cutting blade is of elongated wedge shape with the top of the wedge shape extended all the way to the lower edge of the groove, chopped material does not stick to the knife during chopping; with the absence of a traditional handle and reduced size, the laborsaving back-abrasion-preventive chopping knife is easy to store and may be hung directly to a wall hook.

Description

technical field [0001] The invention relates to a kitchen article, in particular to a novel kitchen knife. Background technique [0002] The handle of a traditional kitchen knife is at the back and the blade is at the front. When cutting vegetables downward, the downward force of the knife handle and the upward reaction force of the blade are not in a straight line. There is a large distance between the two. When cutting vegetables, a torque needs to be applied by the wrist , This will make people feel strenuous and easily fatigued. Therefore, when people are cutting vegetables, their hands will unconsciously move closer to the front of the knife, so that the downward force and the upward reaction force of the blade are as close as possible, so that the vegetables can be cut powerfully and the wrist is not easy to fatigue, but the hand is easily caught by the back of the knife. Wear and tear, especially women's hands are dull and easy to wear and rough. For overcoming abov...

[0002] The handle of a traditional kitchen knife is at the back and the blade is at the front. When cutting vegetables downward, the downward force of the knife handle and the upward reaction force of the blade are not in a straight line. There is a large distance between the two. When cutting vegetables, a torque needs to be applied by the wrist , which will make people feel strenuous and easily fatigued

Therefore, when people are cutting vegetables, their hands will unconsciously move closer to the front of the knife, so that the downward force and the upward reaction force of the blade are as close as possible, so that the vegetables can be cut powerfully and the wrist is not easy to fatigue, but the hand is easily caught by the back of the knife. Abrasion, especially women's hands are boring, easy to wear and rough
