HEINIGER · Snap-On #40

The original Heiniger Snap-On #40 blade lets you choose a specific cutting length with confidence. It is a practical addition to your equipment or a replacement for a worn blade. Check the model designation, cutting length and compatible system below before selecting your blade.

Features in practice

This blade sets the base cutting length of 0.25 mm. Compare the millimetre measurement rather than relying on the blade number alone. Barber blades and animal grooming blades use different numbering systems, so similar markings do not necessarily mean the same length. The blade has its own cutting edges and fits directly onto a compatible clipper. It is different from a guide comb, which fits over an existing blade.

Cutting length and choosing correctly

The chosen cutting length matters when planning the finished look. Shorter blades remove more length, while longer blades leave more hair or coat. Direction of travel, texture and technique also affect the result. If you are unsure, begin with a suitable longer option and shorten gradually. Choosing a different length does not establish mounting compatibility: always check the clipper model and blade type as well.

Blades, combs and compatibility

The Snap-On system changes cutting length by swapping the complete blade. This is useful when alternating shorter and longer areas or keeping a spare blade ready. Check the length in millimetres and attachment system rather than relying on the blade number alone. A metal attachment comb fits over a suitable blade and provides another way to adjust length.

Specifications at a glance

Designed for careful work

Check compatibility with your specific clipper before fitting. Snap-On refers to the matching detachable blade system, not every clipper from a particular brand. Work on clean, combed hair or coat without applying unnecessary pressure.

Care that pays off

Remove hair or coat residue after use and oil the cutting surfaces regularly as directed in the manual. A clean, properly lubricated blade runs more smoothly and maintains cutting quality. Switch the clipper off before changing accessories and check blade temperature during longer sessions.
