Problems solved by technology

[0002] Traditional sharpening stones, sharpening steel rods or rolling grinding wheels are often used for sharpening knives, which is inconvenient to use; the 'quick sharpener' disclosed in Chinese patent 96239439.4 consists of two superimposed sharpening blades intersecting two sharp edges The sides form a double-sided V-shaped sharpening notch; when sharpening the knife, the edge to be ground is placed on the V-shaped notch, the blade is pulled, and the sharp edges on both sides of the V-shaped notch cut the two sides of the sharpened blade. Generate new sharp blades to achieve the purpose of sharpening

Its disadvantages: First, when the blade to be ground is placed in the V-shaped notch, there are three degrees of freedom of rotation relative to the V-shaped notch, that is, the blade to be ground can rotate in all directions relative to the V-shaped notch It cannot be positioned, it is difficult to ensure straight-line grinding, and the quality of the ground blade is not good; the second is that when using this knife sharpener for knife sharpening operation, it is necessary to hold the knife sharpener in one hand and the knife in the other. The blade is potentially harmful to the hand holding the sharpener and is not safe

The third is that this double-sided V-shaped sharpening notch cannot grind a blade with teeth on one side and teeth on the other side, such as a steak knife.
