Description

Figure 0007300118000001
材料を持った側の親指をのせて力点にする為、その背の部分の巾を広くし最適な角度（約３０度）を付け少し湾曲を付け、置いた親指がフィットし長時間の細工作業の指の痛みを大巾に軽減しかつ力強く、かつ正確な仕事が出来るものである。従来のカッターでは背の巾がせまくてすぐ指が痛くなり長時間の作業が出来なかった。けずり作業には絶対必須アイテムである。

Figure 0007300118000001
In order to put the thumb on the side that holds the material and make it a point of strength, the width of the back part is widened and the optimum angle (about 30 degrees) is added to make it slightly curved, so that the thumb can fit and work for a long time. It greatly reduces pain in the fingers of the user, and enables powerful and accurate work. With the conventional cutter, the width of the back was too narrow, and the fingers would soon hurt, making it impossible to work for a long time. Absolutely essential item for scraping work.
