Oster Size 1 Clipper Blade — Professional Detachable, High-Carbon Steel Cryogenically Hardened

Oster Size 1 professional clipper blade delivers salon-grade, ultra-sharp cutting thanks to high-carbon steel construction and cryogenic hardening.

Built to bring consistent, precise results to barbers, stylists, pet groomers and home users, this detachable Size 1 Oster blade is engineered for durability and smooth performance. It fits Oster Classic 76-style detachable blade clippers and compatible models, using a hardened RC62-66 steel core plus proprietary sharpening methods to maintain a keen edge longer than untreated blades. Keep it oiled and clean for best life and use with standard attachment combs to vary cutting lengths.

How does this blade hold up compared with standard clipper blades?

The Oster Size 1 is made from high-carbon steel that undergoes heat treatment and cryogenic processing to raise toughness and edge retention. Those processes reduce wear and preserve sharpness through many trims, so you sharpen or replace blades less often. The finishing techniques also smooth the cutting path for less tugging on hair.

• High-carbon steel hardened to RC62-66 for increased wear resistance
• Cryogenic treatment to stabilize the steel microstructure
• Proprietary edge finishing for smoother cuts and reduced friction

Will the Size 1 blade fit my detachable Oster clipper?

This blade is designed for Oster detachable-blade clippers that accept Classic 76-style cutting heads, including many Titan, Cordless 76, Model One, Model 10 and Outlaw-compatible models. It installs and locks into place like other Oster detachable blades, providing a secure fit for professional workflows. Always check your clipper model compatibility list before purchase to ensure perfect alignment and function.

• Standard attachment combs can be used for adjustable cutting lengths

How should I care for the blade to extend its life?

Routine care keeps the blade performing at its best: clean hair and residue after each use, oil the teeth before and after sessions, and disinfect when necessary following product instructions. Proper lubrication reduces heat and friction, slowing wear and preserving the sharp edge. Store the blade dry and protected to prevent corrosion between uses.

• Brush hair and debris from teeth after each use
• Apply clipper oil lightly before and after cutting sessions
• Use approved blade disinfectants when switching clients or animals

What cutting result can I expect from a Size 1 blade?

A Size 1 blade provides a short, close cut ideal for tapering, blending, and crisp outlining while preserving a small amount of length. Its ultra-sharp profile lets it move through most hair types smoothly, delivering consistent, professional-looking finishes without excessive strokes. Pair with comb attachments for guarded length options.

• Short, close cut suitable for fades, tapers and detail work
• Smooth passage through coarse or fine hair types with minimal pulling
• Combine with combs for longer, customizable lengths
