The Oster size 40 detachable blade is designed for veterinary surgical preparation or use beneath Oster Universal comb attachments. It gives the groomer a named cutting option to select for the coat and finish required.

The blade is made from high-carbon steel and undergoes hardening and cryogenic treatment before its cutting surfaces are sharpened and finished. Its detachable design allows removal for cleaning and replacement within a compatible clipper setup.

Use the exact size marking when selecting the blade. Remove accumulated hair and apply blade lubricant between uses as directed by Oster, and check that the blade fits the clipper being used.
