Production of Sharpening Tools

The iSTOR SWISS SHARPENER^®, including packaging, are 100% Swiss-made. We also, wherever possible, use institutions with secured workplaces.

The secret is in the composition and the shape of the sharpener section. It is as hard as a diamond and is hardly subject to wear. The iSTOR DUPLEX SWISS SHARPENER^® has an additional grinding blade. This allows you to remove small dents on tree shears and other garden implements.

The handle made of aluminium is not only very light-weight but is also excellent for printed logos.
