Abstract: The invention relates to a handle for a hand-operated striking tool including a body having a striking end corresponding to a terminal area. The handle also includes a connection system configured to surround the terminal area of the body at a distance so as to define a space between the connection system and body. The connection system includes at least one access hole to the body on each front surface in the terminal area of the body. At least two securing members are configured to be inserted in the holes of the connection system and to mechanically connect a striking head to the body in an orthogonal direction to the striking head.

Abstract: The invention relates to a manual cutting tool including two jaws each provided with a cutting blade, the two jaws being mounted movable in rotation with respect to a securing system so as to define a closed position and an open position of a cutting area. The tool also includes two cams mounted rotating with respect to the two jaws and each including an aperture, and a bearing surface having a variable curvature, the two bearing surfaces being configured so as to be in permanent connection. The tool includes two connection parts positioned on the axes of rotation of the jaws and configured to connect the cams to the jaws.
