OLFA's 18mm Speed Blades (LFB-10B) are heavy-duty snap-off replacement blades made from premium Japanese carbon tool steel and finished with a special non-stick coating that cuts up to two times faster by reducing cutting resistance. Each ultra-sharp, dual-honed blade is 25% sharper than OLFA's standard silver blades, so it slices cleanly through tough materials like underlayment, foam board, carpet, linoleum, and cardboard. Every blade carries 8 snap-off segments — simply snap off a dulled tip with pliers to expose a fresh, factory-sharp edge. This pack contains 10 blades and fits most standard 18mm heavy-duty utility knives.
