Oster Professional blades are crafted from premium high-carbon steel and meticulously shaped to meet our strict standards, ensuring unmatched precision and performance. Additionally, our blades made in the U.S. undergo hardening to RC62-66 (Rockwell Scale C) in-house before a cryogenic treatment that further strengthens them. The cutting edges of the blades are then honed, polished, and assessed through Oster's established proprietary methods, guaranteeing blades that remain exceptionally sharp over time. They come in a variety of sizes to accommodate different cutting lengths and offer extensive versatility.
