As you screw in, the handle acts like a dice and screws are formed on the file itself. I sometimes want to use a file as well as use it, so it is convenient to remove the handle easily. When reinstalling it, it is good to turn it in the reverse direction and tighten from the sunken place.
Although it was not a file of a screw type, I used it while wearing it by pounding it firmly. The feeling of grasping is easy to use fitted to the hand moderately. It is a plain item, but it is a very important part as it is surprisingly very good feeling.
