Oster Cryogen-X Clipper Blade #30
All of Oster® blades are put through a 12 step process guaranteeing quality and craftsmanship. We start with a fine-grain carbon steel that is heat treated to create a hard surface for greater wear resistance, leveraging a Rockwell Hardness Rating of 62. Our patented Cryogen-X™ process takes the blades down to a -300 degrees for a deep freeze, producing a harder, sharper blade which extends the product life. Each blade is then hand lapped for a smooth cut finish.
- Leaves hair 1/50″ – 0.5mm
- Use between the pads of the feet

The blade cuts very smoothly and stays sharp longer than the previous ones I used. It fits well with my clipper and gives consistent results every time. The precision is noticeable when trimming around the edges.
Pippa Davies –
I’ve used this blade for several months now and it still cuts cleanly. The deep freeze treatment seems to make a difference in how sharp it stays. Works well with the comb attachments.

Great quality and precision. The cut is even and consistent, especially on finer hair. I appreciate the smooth finish and the durability it offers.

It fits perfectly between the feet of the clipper and delivers a clean trim. The blade feels solid and doesn’t dull quickly. Slightly more expensive, but worth it for the performance.
