Abstract
To provide a manual tool excellent in workability and operability and capable of precise tightening torque management, a manual tool includes a grip including a bit holding part that detachably holds a bit, and a torque sensor that is of a magnetostrictive type, and includes a detecting part that is penetrated by the bit held by the bit holding part and surrounds an outer periphery of the bit, the torque sensor is capable of contactlessly detecting a torque acting on the bit, and is detachably provided to the grip. The torque sensor can be configured to be formed so as to be mountable to the grip with the bit mounted to the bit holding part of the grip.
