About us

Rennsteig Werkzeuge GmbH – Always a good connection.

RENNSTEIG has been manufacturing professional hand tools from the idea to a series product since 1959. Today the company employs 315 workers and belongs to the well-renowned KNIPEX-Group since 1991; from that time on RENNSTEIG has developed into a worldwide leading manufacturer of cable processing technology.

One of the priorities is on the processing of turned contacts for aluminum and copper cable used in aircrafts and satellites. In addition to crimping tools, the company specializes in cable cutting and stripping solutions, as well as the processing of polymer optical fiber (POF).
