Keep your long point sharpeners in perfect working condition with this set of genuine KUM 530A replacement blades. Specifically designed to fit the KUM Long point models AS2, AS2M, AS3, 202-24, and 400-5L, these ultra-sharp blades ensure a clean, precise point every time. Each blade is crafted from high-carbon steel and hardened to 65 HRC—making them tougher than most high-end knives or even ball bearings. This exceptional hardness is essential when sharpening pencil cores made from graphite and clay, both notoriously abrasive materials. KUM finishes each blade using a felt wheel polishing process (similar to leather honing) for a razor-sharp edge right out of the pack. KUM has been making high-performance sharpeners in Germany since 1919, and their commitment to quality is clear in every detail—from their choice of carbon steel over inox, to magnesium instead of aluminium or cast metal. These blades also feature KUM’s unique Dynamic Torsion Action, ensuring optimal tension across the blade for consistent results.
