The Heiniger Saphir/Opal Blade Latch is a small but important part of the Heiniger Saphir and Opal cordless clippers. It is the black plastic lock that holds the blade in place, allowing for a smooth and precise clipping of your pet’s fur. The blade latch can wear out over time, especially if the blades are not lubricated regularly or are too tight. This can cause vibration, noise, and reduced performance. To keep your Heiniger Saphir and Opal clippers in optimal condition, it is recommended to change the blade latch periodically. The Heiniger Saphir/Opal Blade Latch is easy to install and compatible with all Heiniger blades.
