SQUARE BLADE: The blade has a square form to it. The blade is made up of stainless carbon steel with zero gaps between the tooth of the blades. | RUST RESISTANT: A cooler and more comfortable smooth-cutting experience is offered by the heat- and rust-resistant close-cutting square blade. | DEEP TOOTH: Longer hair can pass through the blades more quickly because of the high teeth and space between them, making them effective for light fading. | CLOSE-CUTTING: For maintaining a beard, trimmers with attachment combs work great. For fine precision work on hair, beards, and mustaches, close-cutting trimmers are a need. | COMPATIBLE: It is the replacement blade set for trimmer models GO and GTO. It is compatible with the Headliner Shave & Trim LS and Andis T-Outliner or Outliner II Trimmer.
