DUX is the first producer of pencil sharpeners in Germany and opened its doors in 1908. The sharpeners are made of magnesium alloy or solid brass and look so luxurious! To make them, they first drill a hole in a lump of special alloy and then put an edge that is designed to last for 2000 hours of sharpening. This process hasn’t changed since they established the company! We also sell the extra blades, so you can replace it when needed.
