Oster - Cryogen X AgION Size #30 Blade (leaves hair 1/50" )

The Cryogen-X treatment is a tempering process that deep freezes these high-carbonsteel blades to -300 degrees F. Innovative "grooves" have been added to the comb portion to allow for more heat dispersion. The end result is that not only do they start out sharp, they stay sharper longer, requiring less sharpening than conventional blades. These have a Rockwell Hardness Rating of 62. Compatible with all Oster, Andis, Conair and Wahl detachable clippers. Try them and you will see the difference !
