Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to polishing tools such as knives, knives and scissors.

[0002]

2. Description of the Related Art In a conventional sharpener, a grindstone is fixed to one,
It's a little rough, so it doesn't last long. Also, since it uses almost no water, it damages the blade due to frictional heat. Blade spills cannot be sharpened. Depending on the material of the blade, you have to use a sharpener properly.

[0003]

[Problems to be Solved by the Invention] By fixing a blade, holding the grindstone in the hand, and sharpening the grindstone along a grindstone guide line for guiding the grindstone, a constant blade angle is maintained and round grinding is avoided. It has a good sharpness and a long sharpness,
It is a sharpener with the purpose of making it easy and easy for anyone to sharpen.

[0004]

To achieve the above object, the present invention comprises a main body and a pressing lid, and the main body is provided with several magnets for fixing a cutting tool. In addition, a non-slip agent is applied to the main body to fix the blade. The pressing lid is provided with a curved line made of a hard material similar to the cutting edge line of a cutting tool, and a whetstone guide line. The whetstone guide line and the main body cutting edge line are similar curves and are configured substantially parallel to each other.
It is preferable that the lid pressing line is also configured to be parallel to both lines.

A lid pillow is provided between the main body and the holding lid, and there is a gap between the two holding lid adjusting screws and the holding lid, and the holding lid is configured to incline left and right with the lid pillow as an axis. There is.

[0006] In order to adapt to a tool having a different thickness at the base portion and the tip portion such as a cutting knife, a holding lid moving groove is provided to change the distance between the main body cutting edge line and the grindstone guide line. . The pressing lid moves left and right around the adjustment screw of the upper pressing lid in Fig. 1.

In FIG. 3, the main body is in the form of a knife, but as shown in FIG. 4, the upper and lower body blade line parts are opened so that the blade edge of the kitchen knife can be located outside the body blade line. There is. The grindstone guide line and the main body cutting edge line are formed substantially parallel to each other.

[0008]

The blade sharpener having the above-mentioned structure enables the grindstone to be fixed by keeping the distance between the two-curved grindstone guide line and the body cutting edge line and the height of the grindstone guide line including the thickness of the pressing lid constant. When sharpening a blade, the blade angle will be constant, and there will be no round sharpening.

[0009]

EXAMPLES Examples will be described with reference to the drawings. FIG.
In FIG. 2, the horizontal distance between the main body cutting edge line 2 and the grindstone guide line 1 is 35 mm. When the height of the grindstone guide wire 1 including the thickness of the pressing lid 6 is 8 mm, the thickness of the grindstone guide wire 1 is 2 mm.
When the knife 15 of mm is sharpened, the blade angle is sharpened to about 14 degrees. This blade angle changes somewhat depending on the thickness of the blade. The same applies to FIGS. 3 to 4.

1 and 2, when the sharpening hand is right-handed, the knife edge 16 of the knife 15 is left on the left side of the instrument body 3 and the handle 17 of the knife is inserted between the body 3 and the pressing lid 6. Fix in the fixed place 9. The cutting edge 16 is extended to the outside by about 1 mm from the main body cutting edge line 2. The knife 15 is fixed to the body 3 by the magnet 4 provided on the body 3 and the anti-slip agent 12 applied to the body 3.

If a chopstick or the like is pushed into the gap between the holding lid 6 and the main body 3 under the central portion on the right side of the holding lid 6, the holding lid 6 is stable and the kitchen knife 15 is used to hold the kitchen knife 15.
Is further fixed to the main body 3.

Hold a small whetstone soaked in water in your hand and apply force to your fingertips along the magnet guide line 1 from top to bottom and rub diagonally to the right to sharpen. Next, the knife 15 is taken out, turned over, moved to the right side of the main body 3, and the same thing is repeated.
If you are left-handed, you should have a grindstone on your left hand and sharpen from the opposite side.

For small knives and knives with a small curve at the cutting edge, it is advisable to fix the handle of the cutting tool to the handle fixing places 10 and 10 'and sharpen it.

For small knives, knives and the like having a large cutting edge curve, it is preferable to fix the handle of the cutting tool to the handle fixing places 11 and 11 'and sharpen it.

In the case of a right-edged knife that has different thicknesses at the base and the tip of the knife, reversely to the above procedure, loosen the cap adjusting screw 5b a little, and insert the knife on the right side of the main body 3 for the handle. If the handle of the knife is fixed to the fixing place 9'and the lower part of the pressing lid 6 is moved around the pressing lid adjusting screw 5a to the left along the lid moving groove 7, the grindstone guide line 1 and the body cutting edge line 2 Since the distance is large at the base and small at the tip,
When sharpened, the blade angle is almost the same at both the base and the tip.

The holding lid moving groove 7 may be provided on the left side of the holding lid adjusting screw 5b, but the need for it is small because there are very few left-sided blade cutters.

The body 3a, which will be described with reference to the embodiment shown in FIGS. 3 to 4, is of a sheath type. The knife 15a is inserted into the main body 3a, and the handle 17a of the knife is fixed to the handle fixing place 9a. The knife 15a is pushed out by the knife push-out opening 18a, and the blade tip 16a is pushed out by a finger tip to the outside of the main body blade tip line 2a by several mm. In the same manner as above, it is advisable to grind diagonally laterally along the grindstone guide line 1a from top to bottom. Next, the main body 3a may be turned over as it is, and the back surface of the kitchen knife 15a may be sharpened.

[0018]

Since the present invention is constructed as described above, anyone can easily sharpen a blade by using this tool. The blade angle is constant, and there is no sharpening and it cuts well. The grindstone is small and easy to use because you can hold it in your hand. Moreover, the sharpness is long. You can sharpen a knife or knife made of stainless steel or steel. Both blades and single edge can be sharpened, and blade spills can be sharpened by using a rough whetstone. It is also convenient because it can sharpen trimming scissors.

If the knife edge of the knife is stored inside the instrument, it can also be used as a storage tool for the knife.
