22によって形成されるＶ字形溝に庖丁の刃部を入れて前
後に押し引きする。庖丁を下方に強く押せばＶ字形溝は
狭くなり刃を鋭くすることができる。逆に刃部の厚い庖
丁（出刃庖丁など）は溝に緩く当てて押し引きする。(Prior Art) A conventional knife polishing tool has a structure as shown in FIGS. 5 and 6. The support wheels 21 having an inverted V-shape having elasticity are arranged so as to face each other alternately, and a rectangular parallelepiped grindstone 22 is attached to one sloping surface of each support member 21. Wheels alternately facing each other
Insert the blade of the knife into the V-shaped groove formed by 22, and push and pull back and forth. By pressing the knife down strongly, the V-shaped groove becomes narrow and the blade can be sharpened. On the other hand, a knife with a thick blade (ex. Knife, etc.) should be pressed loosely against the groove.

（考案が解決しようとする課題） 従来のように恒久的に固着された直方体の砥石の一面の
みで研いでいると、庖丁の刃縁は常に砥石の１ケ所にし
か当らないからすぐに磨り減ってしまい庖丁を研げなく
なるという欠点があった。(Problems to be solved by the invention) When sharpening with only one surface of a rectangular parallelepiped whetstone that is permanently fixed as in the past, the blade edge of the knife is always worn only at one point of the whetstone, and it is quickly worn down. It had the drawback that it couldn't sharpen the knife.

この考案は、研磨部材に対して刃が当たる所を変えるこ

動することができる。The knife polishing tool shown as an example includes four polishing members 1 to 4.
And a support member 5 that supports them. Support member 5
Is formed into a rectangular parallelepiped using a material such as rubber having elasticity. The support members 5 include the polishing members 1 to 4 described above.
Four circular holes for inserting the holes are formed in the support member 5 in the vertical direction and in the horizontal direction. The polishing members 1 to 4 each have an elongated round bar shape and are made of new ceramic. A high hardness metal or the like may be used instead of the new ceramic. Although the polishing members 1 to 4 of the examples have a length of 6 cm and a thickness of 6 mm, a given purpose can be achieved regardless of the length and thickness as long as the cross section is circular. The round hole of the support member 5 has a thickness that allows the inserted polishing members 1 to 4 to be slightly tightened by its elasticity. Therefore, since the polishing members 1 to 4 are pressed against the knife at the time of use, the polishing members are pressed against the inner wall of the round hole of the support member 5 to increase the frictional force, and the frictional forces support the polishing members 1 to 4. The member 5 is fixed during use. Since the knife is not pressed when not in use, the frictional force between the polishing member and the inner wall of the round hole is not so large.
4 can slide in the axial direction and can rotate about the axis.

The polishing members 1 and 3 out of 4 are inclined to one side,
2,4 are leaning to the other. When viewed from one side, this knife polishing tool has polishing members 1 and 3 and polishing members as shown in FIGS. 1 and 4.
A V-shaped valley 6 is formed between the two and 4. This valley 6
The blade edge can be sharpened by applying the blade portion 7 of the knife to and pushing it back and forth.

The supporting member 5 of the knife polishing tool is tightly fitted into the recess 9 formed at the right end of the mounting table 8. If you are right-handed, the left hand handle 10 with your left hand
The blade edge can be sharpened by pressing and holding the knife with the right hand and inserting the blade portion 7 into the valley portions 6 of the polishing members 1 to 4 and pushing back and forth.

（効果） 本考案は以上のような構成であって、支持部材はゴムの
ように摩擦係数が大きく弾力性のある材料で形成され、
丸棒形の研磨部材を支持するために、支持部材にはその
弾力で研磨部材を締める程度の太さの丸穴が設けられて
いる。(Effect) The present invention has the above-described structure, and the supporting member is made of a material having a large coefficient of friction such as rubber and having elasticity.
In order to support the round bar-shaped polishing member, the support member is provided with a round hole having a thickness large enough to tighten the polishing member by its elasticity.

したがって、研磨部材を支持部材の丸穴の中に挿入した
場合に、支持部材の締め付けは弱く研磨部材を丸穴の中
で回転できるので、研ぎ面を変えることができる。ま
た、研磨部材を丸穴から引き抜いて新しいものと交換す
ることもできる。Therefore, when the polishing member is inserted into the round hole of the support member, the tightening of the support member is weak and the polishing member can be rotated in the round hole, so that the polishing surface can be changed. Also, the polishing member can be pulled out from the round hole and replaced with a new one.

本考案の大きな特徴は、研磨部材がニューセラミックで
形成されているときに顕著である。すなわち、研磨部材

めに研磨部材と内壁との摩擦力が大きくなって研磨部材
が固定されるのである。The major feature of the present invention is remarkable when the polishing member is formed of new ceramic. That is, when the polishing member is made of metal, the processing is easy, and therefore the connection with the support member can be a screw connection. However, new ceramics are difficult to process, and if a notch such as a screw is present, it is likely to be damaged at that portion, so screw connection cannot be used. When the new ceramic is used as a polishing member, its shape must be a simple elongated round bar. The polishing member of the round bar must be rotatable in the round hole and fixed during use. In the present invention, a round hole is formed in a material such as thick rubber, and the polishing member is inserted into the hole, so that the polishing member is pressed against the knife during use to press the inner wall of the round hole, and therefore the polishing member The frictional force with the inner wall increases and the polishing member is fixed.

以上のように、本考案は単純な丸棒形状の研磨部材を支
持部材に対して取り換え可能とし、回動することがで
き、しかも使用時には固定することができるという優れ
た効果を有する。As described above, the present invention has an excellent effect that a simple round bar-shaped polishing member can be replaced with a supporting member, can be rotated, and can be fixed when used.
