Wahl 0.5 Grey Clipper Guard – Color-Coded 1.5mm Guide #3137-101

The step between skin and a #1.

The Wahl #0.5 Grey Clipper Guard #3137-101 cuts at 1/16" (1.5 mm), the guard that bridges a bald or lever-closed pass and a full #1. On a tight skin fade that transition is where lines show, and a half-size is how you make it disappear. Wahl's color-coded system means you find it by grey rather than reading a number mid-cut.

• Kills the line above a skin fade — 1/16" (1.5 mm) fills the hardest transition.
• Instant identification — grab the grey guard without checking numbers.
• Repeatable short lengths so the bottom of your fade is consistent client to client.
• Firm attachment that stays put through a fast pass.
• Standard Wahl full-size fit.

Questions Barbers Ask

What is the difference between a #0.5 and using the lever?

The lever changes the blade itself and takes practice to keep even. A #0.5 guard gives you a fixed, repeatable length — many barbers use both, lever for the very bottom and the guard just above it.

Where does it sit in a fade?

Usually the first guard above the skin or bald section, before you step up to a #1.

Does the color mean anything beyond identification?

No — it is a workflow feature. The grey guard is functionally identical to a black one of the same size.

Why Barbers Love It

The bottom third of a fade is where clients look hardest. Having a true half-size at 1.5 mm is what makes that section read as a gradient instead of a stack of steps.
