In a partnership with German pencil sharpener company KUM, Blackwing presents the perfect tool to get your Blackwing as sharp as possible. The first hole sharpens the wood and the second hole precisely sharpens the graphite core. A built-in stopper acts as an automatic brake, preventing over-sharpening. The sharpener's razor-sharp blades are made of high-carbon steel that resists corrosion and can stay sharp for thousands of uses. Two replacement blades are included in a compartment inside the sharpener. Made in Germany.
