Abstract

To problem such a conventional problem that in a conventional cutter knife, when performing a cutting work by gripping a cutter knife body with a dominant hand (right hand), holding a material to be cut with the other hand (left hand), bringing an inner surface of a left hand thumb into contact with a back part of the tip of the cutter knife as a point of effort, a width of the back is very narrow, a corner thereof hits the inner surface and the same hurts, making it difficult to continue working.SOLUTION: A part surrounded by a dot line in Fig. A, with which an inner surface portion of a thumb is brought into contact as a point of effort, that is a back of a tip of a cutter knife is widened in a width thereof, and slightly curved at an angle of about 30 degrees, whereby long time working can be performed, also a hard wood can be easily cut, and working accuracy is also significantly improved. The wood can be freely cut thinly or thickly by adjusting a force.SELECTED DRAWING: Figure 1

Figure 2022014418000002
In order to put the thumb on the side holding the material and make it a point of emphasis, widen the width of the back part, give an optimum angle (about 30 degrees) and make a slight curve, and the placed thumb fits and works for a long time It can greatly reduce the pain in your thumb, and you can do powerful and accurate work. With a conventional cutter, the width of the back was narrow and the fingers hurt immediately, making it impossible to work for a long time. It is an absolutely essential item for scraping work.
