Adopting "high durability, small size square drive technology". The square drive size goes from 3/4 inch (about 19 mm) to 1/2 inch (about 12.7 mm), so a socket that previously cost 1,900 yen can now be used for just 950 yen. Because it is a standard square drive, it is easy to obtain, and the more you use it, the more you can reduce costs.
