At present, the knife stone is the most common knife edge repairing device on the market, such as a knife stone seat disclosed in the utility model patent with publication number of CN201366663 and an adsorption type household knife stone disclosed in the utility model patent with publication number of CN 208358616U. For the knife grinder, when in use, a user needs to manually rub the knife tool on the top surface of the knife grinder at a certain angle by means of different gestures.
In order to ensure the quality of the edge restoration, a user needs to maintain the cutter at a proper angle all the time in the process of restoring the cutting edge by utilizing the knife sharpening stone, so that the phenomenon of deviation of the sharpening angle of the cutter is avoided as much as possible. However, an auxiliary tool for grinding a cutter such as an existing angle gauge, such as an angle gauge disclosed in the patent publication No. CN207669100U, generally can only make a limited static reference to an initial angle during grinding of the cutter, and cannot provide real-time auxiliary correction of a hand-held grinding angle of the cutter during grinding and braking. This results in that during actual sharpening, the user often only has to ensure that the front few knives are sharpened at the correct angle, which remains unblasted. Therefore, there is a need for an auxiliary device for repairing cutting edges, which can ensure uniform angle after repairing the cutting edges and is simple to operate.
