The Heiniger Jet is a full-thickness shearing cutter intended for use with extra-wide combs. Its design provides the cutter travel needed across a broad comb, making comb width an important consideration when choosing this component for a shearing setup. The Jet is the cutter in the cutting pair, rather than a complete comb-and-cutter set.

Heiniger specifies a thickness of 4.4 mm and identifies specially prepared sharp edges as a feature of this model. The full-thickness designation helps distinguish the Jet when selecting cutters by model and thickness for an established shearing routine. Follow the handpiece's instructions for fitting the cutter, setting alignment and adjusting tension.

After use, clean and dry the cutter thoroughly. Heiniger recommends protecting stored blades with oil and keeping them in a dry environment.
