Oster Detachable Blade No.0A
Oster professional blades are produced from the finest high-carbon steel and handcrafted to our rigorous standards, providing unparalleled precision and performance. Furthermore, our u.s. Made blades are hardened to rc62-66 (rockwell scale c) in-house prior to receiving a cryogenic treatment which further enhances the hardening process. The blade cutting surfaces are then sharpened, finished and tested with proven oster proprietary processes, ensuring ultra-sharp blades that continue to stand the test of time. Available in multiple sizes for various cutting lengths and maximum versatility.
