M+R Mobius & Ruppert Sharpener Blades | Pack of 3 | Various Types

Built for heavy-duty use, these brass pencil sharpeners from Mobius & Ruppert are virtually unbreakable. They're very popular with design professionals and artists.

If you work with a small pocket sharpener, pay attention to sharp blades. Dull blades tear the wood and cause the mine to break easily – especially with the more sensitive coloured pencils.
