However, because people often forget where to store the abrasive, even if the abrasive becomes slightly dull, the actual abrasive work is not often carried out. In addition, polishing requires skill, and it is difficult for amateurs to sharpen the blade with uniform sharpness because the angle between the blade edge and the abrasive material changes, resulting in a rounded blade edge. . For this reason, it is common to cook with a dull knife, resulting in problems such as the texture of the cut surface of the food being disorganized, making it unsightly, and the taste of the food deteriorating.

There is. The side surface of the hardware 9 is brought into contact with the auxiliary fittings 3 or 4 attached to the inclined surfaces 1b and 1c at both ends of the base 1, and the cutting edge surface that requires polishing is aligned with the edge-shaped polishing edge 2a. contact in a direction perpendicular to the Then, while maintaining this state, the hardware 9 is moved back and forth in a direction perpendicular to the paper plane of FIG. 2, and the cutting edge surface is polished with the edge-shaped polishing edge 2a. Since it is edge-shaped polishing, contact polishing stress is concentrated on the linear contact area, resulting in excellent polishing efficiency. Further, the auxiliary metal fittings 3 or 4 support the side surfaces of the hardware 9, which stabilizes the hardware 9 and enables polishing with a constant polishing angle θ between the cutting edge surface and the polishing edge 2a. There is no risk of so-called round sharpening, etc.
In addition, it has many advantages, such as simplifying the polishing work and requiring no skill.

1 to 4 show a first embodiment of the present invention. In the figure, reference numeral 1 denotes a belt-shaped base having a predetermined wall thickness and made of wood, synthetic resin, or the like. This base 1 has a flat surface 1a in its center for attaching an abrasive material 2, which will be described later, and sloped surfaces 1b and slanted surfaces 1b that gradually increase outward from the abrasive material mounting surface 1a side on both end sides. It has 1C. A triangular prism-shaped abrasive material 2 made of high-speed steel or sintered metal is attached to the abrasive attachment surface 1a by embedding or fitting. Abrasive material 2
The specific mounting structure is as shown in FIG. That is, two sides of the triangular prism shape are sunk into the base 1 in a dovetail-fitting manner, and the remaining side 2a projects outward from the abrasive mounting surface 1a of the base 1. The protruding edge-shaped one side 2a is set so that its height is the same as the lowest portion of the inclined surfaces 1b and 1c. Moreover, this one side 2a functions as a polishing edge that actually contacts and polishes hardware. Hereinafter, this one side 2a will be referred to as a polished edge. The inclined surface 1b
Auxiliary metal fittings 3 and 4 are attached to 1c and 1c for making the polishing angle of hardware such as a kitchen knife constant. 5 is a side surface portion on one end side of the base 1,
A safety cover is rotatably attached to this.
This safety cover 5 has a shape that follows the base 1, and is rotated clockwise about the pivot 5a as shown by the arrow in FIG.
If the abrasive material 2 can be forcefully fitted onto the side surface of the end opposite to the pivot shaft 5a, it is possible to hide the abrasive material 2. In this state, the abrasive material 2 is not exposed to the outside. Therefore, contact between the edge-shaped polishing edge 2a of the polishing material 2 and the human body can be avoided, and accidents such as injury to the human body can be prevented.

能である。 To polish the hardware 9 such as a kitchen knife, as is clear from FIG. ), the cutting edge surface of the hardware 9 is brought into contact with the edge-shaped polishing edge 2a in a direction perpendicular to each other. Then, the cutting edge surface of the hardware 9 and the polishing edge 2 of the polishing material 2
Determine the angle formed with a, that is, the polishing angle θ. Thereafter, the hardware 9 may be reciprocated in the direction perpendicular to the plane of the paper in FIG. 2 at this polishing angle θ. As a result, contact polishing stress is concentrated on the linear contact surface between the edge-shaped polishing edge 2a and the cutting edge surface, and an excellent polishing effect can be obtained. In short, it is possible to sharply sharpen a certain range of the entire blade edge surface of the hardware 9 to a uniform sharpness in a short time. Moreover, since the sides of the hardware 9 are supported by the auxiliary fittings 4, stable polishing work can be performed.
The polishing angle θ does not change during polishing.
Therefore, ideal polishing can be achieved. Furthermore, abrasive material 2
Since it is made of high speed steel or sintered metal, it has excellent wear resistance, and even if the cutting edge surface of the hardware 9 is polished with the edge-shaped polishing edge 2a, the polishing edge 2a
It does not wear out prematurely and can be used for a long time.

止する働きもある。 For hardware 9' whose cutting edge surface has a more acute angle, the contact position between the cutting edge surface and the polishing edge 2a of the abrasive material 2 is set farther away from the contact position between the side surface of the hardware 9' and the auxiliary fitting 4. The polishing angle θ' can be made small by determining the polishing angle θ'. Therefore,
Even if the hardware 9' has a sharper cutting edge surface angle, it can be easily polished. During such polishing work, the auxiliary metal fittings 3 or 4 do not function as guides so that the polishing angles θ and θ' are always constant; It also serves to prevent the inclined surfaces 1b and 1c from being worn out.

etc. (front end),
It is devised so that the safety cover 5 can be removed to perform polishing work. That is, the abrasive mounting surface 1a of the base 1 is set as a horizontal surface on the front side (right side in the figure).
The surface is sloped so that the surface is low. As a result, it is not necessary to stand up the machining griddle 8 during polishing, and the stability of the machining griddle 8 is improved, allowing smooth polishing work and good polishing.

For example, a dovetail-type guide rail 11 is provided, and the abrasive material 2 is fitted into the rail 11 so that it can be slid freely, moved to the right or left side of the griddle 8, and fixed at an arbitrary position with a stopper 12. There is. Since the polishing operation is the same as in each of the embodiments described above, a description thereof will be omitted here. Although not shown in the drawings, the safety cover 5 can be attached to this third embodiment as well in the same way as in each of the embodiments described above.

As explained above, according to the present invention, it is possible to polish hardware such as a kitchen knife with a desired constant polishing angle when necessary. In addition, since the contact between the abrasive material and the cutting edge surface of the hardware is linear, and the polishing stress due to the contact is concentrated on the linear contact portion, excellent polishing efficiency can be obtained. In addition, the abrasive material is
It is made of high-speed steel and sintered metal that have excellent wear resistance, and the edge-shaped polished edge will not wear out prematurely, even if it comes into linear contact with the cutting edge of hardware, and it will last for a long time. It is possible to use the period. Furthermore, the abrasive material does not separate from the rest, which saves time and effort in searching for the abrasive material. Furthermore, it can also be used as a stand for abrasives or abrasive materials. In addition, since a constant polishing angle can be obtained using the auxiliary tool, even an amateur can polish the blade edge surface sharply and uniformly. In this case, the auxiliary metal fittings also serve to prevent wear and tear on the inclined surface of the base (the part that comes into contact with hardware). In short, the polishing tool of this invention reduces anxiety about polishing work and allows casual polishing.
It becomes possible to easily ensure that the sharpness of hardware such as kitchen knives always exceeds a certain level, and it is possible to obtain knives that are aligned with the cutting surface of the food to be cooked. Therefore, the taste of the food can be improved visually as well. Furthermore, since it can be easily attached to conventionally existing mats, it is inexpensive and has great versatility.
