周縁４ａに生ずるバリをこの切込面５の形成に
よつて取り去ることができる。(Function) By forming the cut surface 5, it is possible to remove burrs that are generated on the tip periphery 4a when the cutting surface 4 is polished.
（実施例）
まず、本発明の第一実施例を第１〜３図に従
つて説明する。(Example) First, a first example of the present invention will be described with reference to FIGS. 1 to 3.
第１図に示すように円筒状の柄部１には円筒
状の刃部２が嵌着され、この刃部２の先端には
刃先３が形成されている。そして、この刃先３
を皮膚に当てて回転させることにより、皮膚を
円形状に切断することができる。 As shown in FIG. 1, a cylindrical blade part 2 is fitted into a cylindrical handle part 1, and a cutting edge 3 is formed at the tip of this blade part 2. And this cutting edge 3
By applying the tool to the skin and rotating it, the skin can be cut in a circular shape.
この刃先３の内周面には刃付面４が形成さ
れ、この刃付面４の反対側である刃先３の外周
面において刃付面４の先端周縁４ａに若干の切
込面５が形成されている。 A cutting surface 4 is formed on the inner circumferential surface of this cutting edge 3, and a slight cut surface 5 is formed on the tip periphery 4a of the cutting surface 4 on the outer peripheral surface of the cutting edge 3, which is the opposite side of this cutting surface 4. has been done.
かかる刃先３は次のようにして形成される。
すなわち、まず第２図ａに示すように刃先３の
先端に若干の端面３ａを残すか、又は第３図ａ
に示すように刃先３の先端を尖らすように内周
面を研磨して刃付面４を形成する。次に、第２
図ｂ又は第３図ｂの想像線で示すようにこの刃
付面４の先端周縁４ａを若干切断して第１図に
示すように切込面５を形成する。 Such a cutting edge 3 is formed as follows.
That is, first, as shown in Fig. 2a, some end surface 3a is left at the tip of the cutting edge 3, or as shown in Fig. 3a.
As shown in FIG. 3, the inner circumferential surface of the cutting edge 3 is polished to make it sharp, thereby forming a cutting surface 4. Next, the second
As shown by the imaginary line in FIG. b or FIG. 3b, the tip periphery 4a of the bladed surface 4 is slightly cut to form a cut surface 5 as shown in FIG.
このようにして切込面５を形成すると、刃付
面４を研磨したときにその先端周縁４ａに生ず
るバリを取り去ることができる。なお、この切
込面５はごく小さいため、その形成時バリがで
きるおそれはない。 By forming the cut surface 5 in this manner, it is possible to remove burrs that are generated on the tip periphery 4a when the cutting surface 4 is polished. Note that since this cut surface 5 is extremely small, there is no risk of burrs forming during its formation.
次に、第４〜６図に示す第二実施例について
は、前記第一実施例のものが内研磨方式（内刃
付）であるのに対し逆に外研磨方式（外刃付）
にしたものであり、第４図に示すように、刃先
３の外周面には刃付面４が形成され、この刃付
面４の反対側である刃先３の内周面において刃
付面４の先端周縁４ａに若干の切込面５が形成
されている。 Next, regarding the second embodiment shown in Figs. 4 to 6, whereas the first embodiment uses an internal polishing method (with an inner blade), on the contrary, an external polishing method (with an external blade) is used.
As shown in FIG. 4, a cutting surface 4 is formed on the outer peripheral surface of the cutting edge 3, and a cutting surface 4 is formed on the inner peripheral surface of the cutting edge 3, which is the opposite side of this cutting surface 4. A slight cut surface 5 is formed on the peripheral edge 4a of the tip.
そして、まず第５図ａに示すように刃先３の
先端に若干の端面３ａを残すか、又は第６図ａ
に示すように刃先３の先端を尖らすように外周
面を研磨して刃付面４を形成する。次に、第５
図ｂ又は第６図ｂの想像線で示すようにこの刃
付面４の先端周縁４ａを若干切断して第４図に
示すように切込面５を形成する。 First, as shown in Fig. 5a, some end surface 3a is left at the tip of the cutting edge 3, or as shown in Fig. 6a.
As shown in the figure, the outer circumferential surface of the cutting edge 3 is polished to make it sharp, thereby forming a cutting surface 4. Next, the fifth
As shown by the imaginary line in FIG. b or FIG. 6b, the tip periphery 4a of the bladed surface 4 is slightly cut to form a cut surface 5 as shown in FIG.
このようにして切込面５を形成すると、第一
実施例の場合と同様に、刃付面４を研磨したと
きにその先端周縁４ａに生ずるバリを取り去る
ことができる。 By forming the cut surface 5 in this way, it is possible to remove burrs that are generated on the tip periphery 4a when the cutting surface 4 is polished, as in the case of the first embodiment.
なお、第７図に及び第８図に示す第一実施例
の別例、第９図及び第１０図に示す第二実施例
の別例はそれぞれ刃部２をテーパ状にしたもの
であり、刃先３の構成は全く同様である。 In addition, the other examples of the first embodiment shown in FIGS. 7 and 8 and the other examples of the second embodiment shown in FIGS. 9 and 10 each have a tapered blade portion 2, The configuration of the cutting edge 3 is completely the same.
