Abstract

PROBLEM TO BE SOLVED: To make the cutting edge of a kitchen knife possible to be held positively in a proper angle by means of this tool when the kitchen knife is sharpened using a grinding wheel. SOLUTION: Threaded holes 2, 3 are provided on both sides of an arm 1, a backing plate 4 and a locking screw 7 are attached to the screw part of the threaded hole 2, and a threaded shaft 6 of a caster is installed in the screw part of the threaded hole 3 and a locking nut is attached.

Description

Detailed Description of the Invention

[0001]

[Industrial application] This tool relates to sharpening a kitchen knife with a grindstone.

[0002]

2. Description of the Related Art Conventionally, a hand holding a knife handle is used to hold a grindstone at the same angle as the blade, and the other hand is used to hold the blade for sharpening, but this work requires a high level of skill. .

[0003]

The person who uses the kitchen knife is
Most of them are women and girls, but they were designed so that they could be sharpened easily and accurately without requiring advanced skills.

[0004]

[Means for Solving the Problems] Screw holes for fixing a knife (2) and for adjusting an angle (3) are provided at both ends of an arm (1),
Attach the knife support plate (4) to the arm (1) on the fixed side of (2), and install the threaded shaft (6) of the caster in the screw hole for angle adjustment, and rotate it to rotate the blade. It is a knife sharpening device that can change the inclination.

[0005]

[Function] This tool is fixed in the middle of the back of the kitchen knife, and the blade is placed on the whetstone surface. Then, the adjusting shaft (6) is rotated to move up and down, the blade angles are adjusted, and the fixing nut (8) is tightened and fixed.

[0006]

[Example] To sharpen a knife using this tool, place it so that the whetstone surface is flush with the sliding surface of the caster, grasp the handle of the knife with one hand, and use the other hand to properly cut the blade edge. While holding down, move it back and forth to grind. When sharpening the other side,
Replace the knife fixing part so that the caster (5) is placed on the sharpening side. Further, the pulley (9) of the caster (5) moves better when the shaft (6) is perpendicular to the floor surface, so the arm (1)
Fold it up to the angle of the blade. Furthermore, if the grindstone is too high,
If the adjusting shaft (6) cannot handle it, place a piece of plate of equal thickness under the pulley (9). If necessary, you can change the fixed position of the knife and sharpen.

[0007]

[Effects of the Invention] By using this device, it is possible to sharpen sharply without advanced technology. Also, since the work can be done without the hand or arm being aware of the angle of the blade, there is little fatigue. In addition, because the left and right sides of the grindstone are used for sharpening, it is possible to prevent one side of the grindstone from slipping. Further, not only a knife but also a similar knife can be used.
