[Conventional technology and its problems]

Conventionally, when polishing the cutting edge of a knife or other cutlery,
Depending on the condition of the cutting edge surface and the progress of the polishing work, it is necessary to select a whetstone for rough grinding, a whetstone for semi-finishing, a whetstone for finishing, etc. for polishing, and it takes a lot of time to prepare and store the whetstones. There was a flaw that made it necessary. Moreover, since each type of whetstone is selected and used, their management is often individualized, and each type of whetstone is stored separately, making it extremely difficult to find it when reusing it. there were.

In addition, during this type of polishing work, water is frequently poured onto the polishing surface of the whetstone and the cutting edge surface of the material to be polished to ensure smooth polishing and to prevent the sharpness of the cutting edge surface from becoming dull due to annealing caused by heat generated during polishing. It was necessary to prevent it. For this reason, the polishing work itself becomes complicated, causing undesirable problems such as circular grinding, etc., and requiring skill for the polishing work. In view of this, we have developed a polishing block that has been improved and removed, and can perform many types of polishing operations with one polishing tool, and can also omit water pouring work, and a polishing tool using this block. This is what we intend to provide.

A perspective view showing the state, and FIG. 3 is a cross-sectional plan view of the polishing tool 2. As shown in the figure, in this embodiment, the polishing block 1 is formed into a cube by bonding different types of grindstone pieces 3a to 3f, and each grindstone piece 3a to 3f has water passage holes 4a to 4.
f is drilled. The internal space of each grindstone piece 3a to 3f is filled with a water-absorbing material 5 such as a sponge. The polishing tool 2 has a handle 6 formed by bending and forming a wire material, and a bifurcated pivot 7 formed continuously at the tip of the handle 6, and ends 7a and 7b of the bifurcated pivot 7 are connected to the polishing block. The water holes 4e and 4f of the opposing grindstone pieces 3e and 3f of the grinding wheel 1 are penetrated and installed. Therefore, the polishing block 1 is rotatable relative to the bifurcated pivot 7.

Each of the grindstone pieces 3a to 3f is made of cemented carbide tool steel or diamond for rough pickling, semi-finishing or finishing.

Arazuke made by blending a single powder or mixed powder such as ceramic with synthetic resin as a binding material.

It is for semi-finishing and finishing. In this embodiment, the whetstone piece 3a is for rough sharpening I, the whetstone piece 3b is for rough sharpening ■, and the whetstone piece 3 is for rough sharpening
c is for medium finishing I, whetstone piece 3d is for medium finishing ■, whetstone piece 3e
is for finishing I, whetstone piece 3f is for finishing ■, whetstone piece 3a is for finishing
The grain size of the abrasive grains decreases in the order of 3f to 3f.

Next, the case of polishing the cutting edge surface of a kitchen knife using the polishing tool 2 will be explained with reference to FIG. 2.

First, before starting polishing, the entire polishing block 1 is immersed in water, and the water-absorbing material 5, such as a sponge, filled in the internal space of the block 1 is made to sufficiently absorb and retain water. From this state, as shown in FIG. 2, one of the grindstone pieces 3a to 3f of the polishing block 1 is selected depending on the state of rust on the blade edge surface 8a, the state of the blade being chipped, etc. Assume now that the shape of the cutting edge surface 8a needs to be corrected due to large abrasion deformation of the cutting edge surface 8a, and that the grindstone piece 3a for rough pickling is selected. After selecting the whetstone piece 3a, select the whetstone piece 3a.
The polishing block 1 is rotated around the ends 7a and 7b of the bifurcated pivot 7 so that point a is located on the lower surface of the polishing block 1. Then, the whetstone piece 38 for rough pickling (3) is brought into contact with the blade edge surface 8a, and while gripping the handle 6, the blade edge surface 8a is polished by reciprocating in the directions of arrows A and B.
Make a rough correction to a. At this time, a water passage hole 4 formed in the grindstone piece 3a is provided on the contact surface between the cutting edge surface 8a and the grindstone piece 3a.
The water that has been absorbed into the water-absorbing material 5 from a is injected by the vibrations accompanying polishing.

Therefore, the operator does not need to pour water during polishing, and the polishing operation itself becomes extremely easy. After that, the grindstone pieces 3b to 3f may be sequentially positioned on the lower surface side of the polishing block 1 to perform the desired polishing operation. In this way, in this embodiment, many types of polishing operations can be performed successively using the same polishing tool 2, which is very convenient.

By the way, when moving from the polishing work of each step to the next polishing step, such as when moving from rough pickling ■ to rough pickling ■, each time, the entire polishing block 1 is immersed in water, and the water absorbing material such as a sponge is Water may be supplied to the adhesive material 5. When performing finishing I and H polishing operations, the ends 7a and 7b of the bifurcated pivot 7 are expanded and pulled out from the water holes 4e and 4f, and the other opposing water holes 4a and 4c or Hole 4
