Since the engagement piece 7 on the b side is fitted and fixed, the tip 2b of the handle 2 attached to the grip portion 2a moves up or down or swings around the guide core 6. The handle 2 is restrained, and the tip 2b and the grip 2a of the handle 2 are satisfactorily held in a state where they are straightly extended in the longitudinal direction of the handle 2, and the slit 2 on the grip 2a side has the handle 2a.
When the engaging piece 7 on the distal end 2b side is fitted, the engaging groove 12 formed on the entry side of the slit 11 engages with each engaging projection 9 formed on the base 8 of the engaging piece 7. As a result, the tip 2b of the handle 2 with respect to the grip 2a is securely prevented from being pulled out.

Furthermore, since the separated end of the tip 2b of the handle 2 is positioned in the width direction with respect to the separated end of the grip 2a,
The displacement in the width direction at the mounting portion between the tip portion 2b of the handle 2 and the grip portion 2a is reliably prevented.

Further, while the grip portion 2a is being gripped, the finger hook portion 13 is pushed out by the thumb or the like in a direction in which the tip portion 2b of the handle 2 is pulled out, so that the engagement between the engagement groove 12 and the engagement projection 9 is stopped. Since it is possible to release and to separate the tip 2b of the handle 2 from the grip portion 2a, the danger of the finger touching the blade 3 attached to the tip 2b of the handle 2 is reliably avoided.

Therefore, according to the above embodiment, the mounting state of the tip 2b and the grip 2a of the handle 2 can be favorably maintained by the stopper mechanism 5 and can be used without hindrance similarly to the conventional razor tool 1. In addition, when the sharpness of the cutting edge 3a drops, only the tip 2b of the handle 2 can be replaced with a new one, so that the grip portion 2a of the handle 2 can be used repeatedly, so that problems and resources of garbage disposal can be effectively reduced. A razor tool 1 preferable from the viewpoint of utilization can be realized.

In particular, if the stopper mechanism 5 as shown in the present embodiment is adopted, the tip 2b of the handle 2 mounted on the grip 2a moves up or down, or the head 2 swings around the guide rod 6. And the handle 2 can be restrained, and the tip 2b and the grip 2a of the handle 2 can be satisfactorily held so as to be in a state of being straightly extended in the longitudinal direction of the handle 2, and further, the handle with respect to the grip 2a side. 2 can reliably prevent the tip 2b of the handle 2 from being pulled out.
Even if a is divided, it can be used safely while maintaining the same usability as before.

Furthermore, since the cut-off end of the tip 2b of the handle 2 can be positioned in the width direction with respect to the cut-off end of the handle 2a, the width of the handle 2 in the width direction at the mounting portion between the handle 2a and the grip 2a can be determined. Blurring can be reliably prevented, and safety during use can be further improved.

Further, by simply pushing the finger hook 13 with the thumb or the like in the direction in which the tip 2b of the handle 2 is pulled out while holding the grip 2a, the engagement between the engaging groove 12 and the engaging protrusion 9 can be easily performed. And the tip 2b of the handle 2 can be separated from the grip 2a, so that the risk of finger touching the blade 3 attached to the tip 2b of the handle 2 can be reliably avoided.

Further, as shown in FIG. 5, if it is easy to release the engagement of the engagement groove 12 with the engagement protrusion 9 on the abdominal side, the force is applied from the back side by pushing the finger hook 13 with the thumb or the like. Even if it is applied, the engagement of the engagement groove 12 with the engagement protrusion 9 on the abdominal side to which no direct force can be applied can be easily released, and the tip 2b of the handle 2 can be easily separated.

Further, since each of the engaging projections 9 and each of the engaging grooves 12 are locked by four point contacts of the upper and lower points, it is possible to prevent rattling when both are locked.
