The ISTOR AG company was founded in 1964 in the town of Frauenfeld, Switzerland, by Josef A. Schefer (†).
The focus of activities was on producing advertising gifts during the first 30 years. The ISTOR AG company was one of the first Swiss companies which imported textiles and bags from the Far East. Its customers included Swiss banks and leading industrial and trading companies.
In the early nineties, Josef A. Schefer invented the original istor SWISS SHARPENER®. This sharpener is 100% Swiss-made and its impressive features are its quality and its universal functionality. As a useful tool for the home, the garden and when working, it is very popular world-wide.
The ISTOR AG company is still a family-owned business and the second generation has taken over.
The original istor SWISS SHARPENER® brand has stood for Swiss quality for around 20 years now. Today, the ISTOR AG company has representatives for its products in over 50 countries.
The ISTOR AG company has continually expanded its range of sharpeners. Customers can choose from three models today: standard, professional and duplex.
The ISTOR AG company also has other first-class equipment in its range. Thanks to our many years of experience in production and the trade, we are also able to find tailor-made solutions and products for partners.
