A power tool including a moveable piston, a motor capable of driving the moveable piston to perform work on a work piece, and a distance sensor configured to sense a movement of the moveable piston. The distance sensor operable to provide sensor information indicative of the movement of the piston. A controller receives the sensor information from the distance sensor. The controller operates the motor to perform work on the work piece based in part on the sensor information that the controller receives from the distance sensor.

The present invention relates to a device for mounting a tool on a hand of a user, the device comprises a receiving part for attachment of a tool and at least one mounting member for mounting the device on one or more fingers of the hand of the user, such as two neighbouring fingers, wherein the receiving part is fixed to the mounting member, and the receiving part comprises at least one clamp for clamping a tool to the device, wherein the clamp has a closed position (h2) and an open position (h1) and wherein the clamp is configured to be operable by one or more of the fingers of the same hand the device is mounted on. The invention further relates to a method of mounting a tool in the device, and to the use of the device.

A cutting device is disclosed. The cutting device has a body member formed from a first material and including a cavity extending along a length of the body member from a first end of the body member to a second end of the body member that is disposed on an opposite side of the body member as the first end, a cutting assembly formed from a second material and attached to the body member, the cutting assembly including a protrusion, and a cutting member disposed on the cutting assembly. The body member includes an aperture extending from the cavity to a third end of the body member that is disposed between the first and second ends. The cutting assembly is attached to the body member based on the protrusion being received in the aperture. The first material is more flexible than the second material.

A utility instrument is in the form of a cutting tool suitable for fitting onto a user's finger. The tool has a blade and a sheath, both coupled to a mounting structure. The blade and sheath are pivotable with respect to each other. A user can wear the tool on a finger about a finger joint. The user can bend the finger to set the tool to an open condition to expose the blade for use, and can stretching the finger to set the tool to a closed condition to safely shade the blade using the sheath. The tool may further have a housing for fully receiving the blade. The blade may extend out of the housing for use, and may be retracted into the housing for safety.

Embodiments, alternatives and variations of a device with a assisted opening and closing mechanism for the opening and closing of at least one shaft. Finger rings and other items is configured with components to conveniently, easily and quickly open and close at least one shaft with at least one tensioning mechanism. Other uses of said devices comprise use as a knife, as a tool, a way of relaxation, for therapeutic use, for educational use, as a toy, for self defence, and for entertainment purposes.
