  • the bead can be arranged on the sleeve and the recess on the base body or vice versa. Also several beads and depressions are possible.
  • the middle part and the cuff are connected to one another by means of a frictional connection, which can be generated in particular by elastic stretching of the cuff. A shrinking of the cuff is possible, as well as the combination of several types of connections.

  • the largest diameter of the tool or the tool holder is in the region of the at least one jacket element, ie in the region of the middle part. If the user places the tool or the tool holder on a flat surface, then it rests on the surface in the region of the at least one jacket element. If this has a rougher surface than the body, the tool is better protected against rolling away.
