  When performing universal tapering using the universal hair tapering leather of the present invention, as shown in FIG. 8, the hair bundle to be tapered, that is, the hair panel HP, is the middle finger LM of the left hand and the left hand. When sandwiched between the index finger LF and the head is erected vertically as shown in FIG. 9A or 9B, the hair root side bottom PB is left or right with respect to the vertical direction, for example, 45 ° downward. In addition, the hair is trimmed using a comb so that the hairs from the panel bottom side PB to the hair tip side tip side PT are equal in length.

  FIG. 10A shows a constant blade angle with a predetermined length toward the front end side PT of the panel thus prepared, that is, the inclination angle θ1 is in a range of 0 ° <θ1 ≦ 40 °. The step of performing the tapering operation while maintaining the blade angle is shown. As described above, the inclination of the panel HP may be in either the right or left direction. Tapering is performed while applying a constant tension in the direction.

  FIG. 10B is a cross-sectional view for explaining in principle the actual operation when tapering is performed using the universal hair tapering leather of the present invention. For convenience of explanation, the tapering restriction member 1s is omitted in FIG. 10B.

  As described above, tapering using the universal hair tapering leather of the present invention is performed as follows.

  As shown in Fig. 10A, while applying a constant tension to the hair panel HP in the direction from the arrow U to the arrow D, that is, from the hair root side to the hair tip direction, the reference sword of the blade part 1 on the front side of the panel HP The flat part 1e of the shoulder 1c is brought into close contact, and at the same time, the index finger LF of the left hand is brought into close contact with the front side of the panel HP. Holding the part 3, the blade part 1 is moved from the arrow U to the tapering direction indicated by the arrow D.

  Here, the flat portion 1e of the reference sword shoulder portion 1c prepares the surface of the panel HP to be tapered and functions to keep the inclination angle θ1 of the cutting edge 1a with respect to the surface of the panel HP constant. In cooperation with the middle finger LM of the left hand that supports the back side of the taper surface, the taper condition of the panel HP is always made constant. Thereby, when the universal hair tapering leather of the present invention is used, it is possible to taper by arbitrarily selecting the length of the panel while maintaining a predetermined blade angle.

  In the universal hair tapering leather according to the present invention, when the inclination angle θ1 of the blade 1a is in the range of 0 ° <θ1 ≦ 40 ° as described above, each panel is tapered using this. The tip of lies on a smooth continuous line as shown in FIG. In order to perform such universal taper, preferably 10 ° ≦ θ1 ≦ 35 °, more preferably 20 ° ≦ θ1 ≦ 32 °, and still more preferably 28.5 ° ≦ θ1 ≦ 29.5 °. When the inclination angle θ1 is out of the range 0 ° <θ1 ≦ 40 °, for example, when θ1 is 45 °, at least one of the four conditions necessary for performing universal hair tapering. If one is not satisfied, the hair bundles as shown in Fig. 13 are impossible.

  Here, the tapering regulating member 1s is provided along the cutting edge 1b of the blade 1a as shown in FIG. 5D. Accordingly, as shown in FIG. 10C, when the taper is performed as described above, the cutting edge 1b is brought into contact with the hair at a predetermined interval corresponding to the interval between the protruding edge portions 1sp of the tapering regulating member 1s. The tapering is regulated at a predetermined interval. The distance between the adjacent vertices of these protruding edges 1sp is about 4 mm, each part of the cutting edge 1b that actually contacts the hair is about 2 mm, and the distance to the top of the protruding edge 1sp protruding from the cutting edge 1b is Preferably it is about 1 mm.

  Furthermore, in the universal tapering using the universal hair tapering leather of the present invention, as shown in FIGS. 9A and 9B, the lower end side PB of the hair panel is, for example, 45 ° with respect to the vertical direction. When making it downward, when making it to the lower left or the lower right, the right and left hand stance is exactly the same, and it does not cause any tension on the wrist or arm on either side. The operator may perform this tapering with a natural posture that simply moves the center of gravity of the body in the tapering direction with the right and left hands. As shown in FIGS. 4A and 4B, the handle portion 3 gripped with the right hand is provided to be inclined to the downstream side in the tapering direction with respect to the blade portion 1. As shown in FIG. 4B, the longitudinal center line 3n of the handle 3 is designed to be the longitudinal center line 1m of the blade 1a, and the inclination angle θ2 is in the range of 10 ° ≦ θ2 ≦ 40 °. Because. For this purpose, the inclination angle θ2 is preferably 25 ° ≦ θ2 ≦ 35 °, and even more preferably 28 ° ≦ θ2 ≦ 33 °.

  Furthermore, as described above, it is preferable that the front side surface 3a of the handle 3 has an inclination angle θ3 in the range of 0 ° <θ3 ≦ 40 ° with respect to the reference plane 1g. The tilt angle θ3 is more preferably 10 ° ≦ θ3 ≦ 35 °, more preferably 20 ° ≦ θ3 ≦ 32 °. Is even more preferred.

  By setting the inclination angle θ2 and the inclination angle θ3 in the above ranges, the tapering operation with a natural posture that does not cause any tension on the wrist or arm of the operator is made more reliable.

  This is a unique tension on the hand, wrist or arm as shown in FIGS. 3A and 3B, which was difficult to avoid when using leather as shown in FIGS. Or it is said that it is an occupational illness of a hairdresser or barber who has been inevitable for a long time, and it will free them from tendonitis.

  FIG. 10D shows the front end of the panel when tapered in this way.

  FIG. 11 is a photomicrograph of the tip of the cut hair when tapering is performed using the universal hair tapering leather according to the present invention. As can be seen from this photograph, when the universal hair tapering leather according to the present invention is used for tapering, the hair tip contained in the panel is tapered at a certain angle, and the cut surface is smooth. It can be seen that it is.

  FIG. 12 is a photomicrograph of the tip of the cut hair when tapering is performed using a conventional leather. As can be seen from this photograph, when tapering is performed using conventional leather, the cutting angle of the hair tip contained in the panel is not constant, and the cut surface is not smooth.
