KUM long point manual pencil sharpener. For an extra-long, extra-smooth tip. Sharpens the wood casing first, then the pencil lead, in 2 separate precision profile holes for standard and draftsman points. Automatic stop feature prevents over sharpening. Flexible blades use Dynamic Torsion Action (DTA) to reduce pencil tip breakage. DTA handles the difficult dual task of cutting hard graphite while shaping soft wood while remaining rigid when required and flexing when needed. The blades are protected against rust by careful polishing, eco-friendly ultasonic cleaning, and by a micro-thin oil coating. They are long-lasting and very sharp. High-carbon steel cutting blades. Draftsman plastic pencil sharpeners include 2 spare blades. NOTE: Will NOT accept KUM 530S replacement blades. KUM AS2K long point pencil sharpeners are made in Germany.
