SOLUTION: In an edged tool grind holder composed of a holder main body 1 which is formed of a material having corrosion resistance such as stainless steel or synthetic resin and elasticity and is sandwichedly fixed to the back of a kitchen knife in an elastic part 1a, and a new ceramic protecting plate 2 which is stuck fast to a part coming into contact with the grindstone of the holder main body 1 and has corrosion resistance and sliding ability, the tip side of a sandwiching part 1c for sandwichedly holding the back of the holder main body 1 and both right and left sides on the tip side are severally formed in an inclined face 1d inclining in a direction where mutual tips are expanded.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sharpening holder for a knife, which is attached to a ridge of a knife such as a kitchen knife and is used in contact with the grindstone when the tool is sharpened with the grindstone.

[0002]

2. Description of the Related Art A conventional sharpening holder for this type of blade is
It is proposed in Japanese Utility Model Publication No. 63-9416, which is related to the applicant's application. The blade sharpening holder according to the above-mentioned proposal is elastically held by the peak of the blade when the blade is sharpened with a grindstone.

When the blade is sharpened, a protective plate made of new ceramic is brought into contact with the grindstone to keep the angle between the blade edge of the blade and the grindstone constant so that the sharpened blade does not become a round blade. The sharpness of the sharpened blade and this sharpness can be secured for a long period of time.

[0004]

As is apparent from the drawings of the publication, the blade sharpening holder is continuously provided from the side end of a spring portion bent into a substantially circular shape that imparts elasticity to the holder body. The holding part has a flat surface.

Therefore, in the case of a knife in which the spine and the front end side are cut by the thickness of the knife such as a cleaver, or a knife in which the cutting edge and the ridge do not intersect, such as a cutting knife, The nipping portion hits the ridge of the blade, making it difficult for the sharpening holder of the blade to fit on the blade.

[0006] Further, when sharpening the blade, the clamping of the peak of the blade by the clamping portion requires a certain degree of strength in order to prevent the blade holder from falling off due to frictional resistance with the grindstone. Even if an attempt is made to open the nipping portion with the nipping force, the nipping part cannot be easily opened, and thus there is a drawback that it is difficult to fit into a kitchen knife or the like.

In the present invention, the conventional sharpening holder for blades is
An object of the present invention is to provide a sharpening holder for a blade that can be easily fitted to such a blade that has a sharp peripheral edge other than the blade, and can be easily fitted to such a blade.

SUMMARY OF THE INVENTION The present invention relates to a tool sharpening holder means capable of achieving the above-mentioned object, which means is made of a material having corrosion resistance and elasticity such as stainless steel and synthetic resin. , A holder main body which is sandwiched and fixed to a crest portion such as a kitchen knife due to its elasticity, and a wear-resistant and slippery new ceramic protective plate fixed to a portion of the holder main body that comes into contact with a grindstone In a sharpening holder of a blade made up of the above, the tip side of the upper and lower portions for sandwiching and fixing the ridge of the holder body, and the left and right sides of the tip side are inclined in a direction of expanding each other. .

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to the drawings. In this embodiment, the holder body 1 made of a material having corrosion resistance and strong elasticity such as stainless steel and synthetic resin is formed to have a length of about 5 cm. It is desirable to make various changes depending on the size.

The shape of the holder body 1 as viewed from the side is a spring portion 1a curved in a substantially semicircular shape, a flat portion 1b extending from both upper and lower sides thereof, and a tip end substantially continuous with the flat portion 1b. Beak-shaped holding portion 1c maintained in contact
And formed.

A protective plate 2 made of new ceramic, which is excellent in abrasion resistance and slidability, is adhered to the flat portion 1b with an adhesive having high water resistance. Then, from the spring portion 1a of the holder body 1, the holding portion 1c is fitted to the ridge of the blade, and the holder body 1 is attached to the blade A.

While the protective plate 2 is in contact with the grindstone, the blade edge is applied to the grindstone and the blade is slid back and forth to sharpen the blade edge, but the protective plate 2 is worn in contact with the grindstone. Has a role to prevent.

The holder body 1 keeps the angle between the cutting edge and the grindstone constant, and prevents the cutting edge from becoming a round blade that loses its sharpness at an early stage by grinding,
The entire cutting edge is flat, and the cutting edge is sharpened at a constant angle, enabling sharpening to be maintained for a long period of time.

The above is the blade sharpening holder described in the above publication. The blade sharpening holder does not slip or come off from the blade when the blade is attached to the blade and sharpened. The elasticity due to 1a must be such that the clamping force when mounted on a blade is quite strong.

Therefore, when it is attached to a cutting tool such as a kitchen knife which has a vertical surface other than the cutting edge, the end of the holding portion 1c does not hit the vertical surface and does not open. Since it is difficult to open the blade due to the strong gripping force, it was difficult to attach it to the blade.

In the present embodiment, the inclined surface 1d is such that the front ends of the upper and lower sandwiching portions 1c are successively opened.
Alternatively, since it is a circular arc surface, this inclined surface 1d hits the edge of the vertical vertical surface of the cutting tool, so if the holder body 1 is strongly pressed against the peak or tip of the cutting tool,
As described above, the inclined surface 1d or the arcuate surface is pushed in the direction in which it spreads due to the contact with the contact corner portion such as the peak portion of the cutting tool, so that it can be opened.

[0017]

As described above, the conventional sharpening holder for a cutting tool can be easily attached to a vertical surface with a sharp edge other than the cutting edge such as a cutting knife, or a cutting tool where the cutting edge and the ridge do not intersect. According to the present invention, however, since the tip end sides of the upper and lower nipping portions that are fitted to the blade of the blade holder holder of the blade sharpening tool are tilted in the directions of expanding each other, the holder body is strongly pressed against the sharp edge of the blade. This will allow the slope to open.

For this reason, only by sloping the peripheral edge of the sandwiching portion as described above, it becomes possible to easily mount the blade on a blade which is a vertical surface which is sharp except for the blade edge, which has been difficult in the past. Since there is no cost in forming the surface, the cost is not increased.
