The Heiniger #40 snap-on blade set provides a 0.25 mm cutting length and fits all Heiniger Saphir and Opal clippers. It is intended exclusively for veterinary use, as specified by Heiniger. The current manufacturer specification is the red line version, made from tool steel with a chrome finish. Its revised grinding and hardening processes are designed to support cutting consistency.

The blade uses the A5 snap-on system, which also permits use on other clippers built for that fitting. Match the blade number and cutting length to the required job when selecting a replacement.
