Oster uses cryogenic technology to create the hardest clipper blades ever. The Cryogen-X treatment is a tempering process that deep freezes these high-carbon steel blades to -300 degrees F, so molecules are aligned in a perfect structure. The result is a harder, denser metal that holds a sharper edge through prolonged usage. The Cryogen-X Blades also withstand more sharpening treatments for unsurpassed longevity. Sharper blades glide through coats with less effort, saving you and your clipper from unnecessary fatigue and wear. Innovative "grooves" have been added to the comb portion to allow for more heat dispersion. These blades are the coolest running blades ever offered from Oster and are up to 20 degrees cooler than standard A-5 blades.
Cryogen-X Blades are manufactured from fine-grain, high-carbon steel and the cutting teeth are machined to exact specifications for the best possible results. Compatible with most Oster, Andis, Conair and Wahl detachable clippers.
FYI: The higher the Blade Size Number, the closer the cut. ie: The size 4 blade leaves more hair on your dog and the Size 40 takes the most hair off (surgical cut).
