KUM #430-M2 Transparent Barrel 2-Hole Pencil Sharpener

KUM #430-M2 Transparent Barrel 2-Hole Pencil Sharpener Double hole translucent barrel sharpener. Screw-on lid prevents pencil shavings from falling out. Premium artist's quality magnesium sharpener for use with graphite, colored and watercolor pencils and pastel crayons. Suited for pencils up to 8 mm in diameter (standard #2 style pencils) and for thicker pencils up to 11 mm in diameter. Replaceable quality blades are made of specially hardened steel. Made in Germany. KUM Blades: All KUM sharpeners are equipped with ultra hard (65 hrc) and razor sharp high carbon steel blades. These blades are harder than ball bearings or any high quality knife. This is needed because pencil leads are made of a mixture of graphite and various types of clay, which are extremely hard. Each blade is razor-sharp. A felt sharpening wheel (similar to leather) is used as the last step in the automatic sharpening process.
