1924	Scissors grinder Wilhelm Kretzer becomes self-employed in a delapidated cottage on Katternberg in Solingen. He accepts commissions to make all types of scissors.
1943	His son Willy Kretzer takes over the business with his wife Leni in World War II. They expand the contract production business to manufacture all types of pedicure and manicure articles, in particular tweezers.
1968	Wolfgang Kretzer, the grandson of the company founder, takes over the company. He concentrates on manufacturing tweezers and expands the company continuously. He buys in forge hammers and punching machines. The company produces the raw materials it requires itself. The transition from commission work to vertical manufacture takes place. Exports are increased and turnover increases. In the mid 1980s the company begins manufacturing files for corns. In the 1990s Wolfgang Kretzer constructs fully automatic machinery for the manufacture of tweezers. These enter operation and are successful.
1998	Following the sudden death of Wolfgang Kretzer, his daughter, Barbara, takes over the company aged 25. She is the 4th generation in the family firm and she has managed it to this day together with her husband Markus Austrup.
2004	The property at Dingshauser Str. 19-21 in Solingen is acquired on the 80th anniversary of the company. The company relocated there early in 2004. Since that time the company has had 650m² of production floor space and office space.
