Hit Point

Hit Point (ヒットポイント)

Quick look

  • What it is: The exact point where the two blades make contact during a cut
  • Why it matters: Determines whether hair is cleanly cut or folded/pushed
  • Moves from: Heel to tip as the scissors close
  • Adjustment: Controlled by blade tension and blade alignment

Why it matters

The hit point is one of those concepts that Japanese scissor training considers absolutely fundamental but that Western hairdressing education barely covers. It’s the precise location where your two blades meet and where cutting actually happens. As you close your scissors, this contact point travels from the heel (near the pivot) toward the tip.

When the hit point is correctly aligned, hair is sliced cleanly at the exact moment it’s trapped between the blades. When it’s off, hair gets pushed, folded, or bent before it’s cut. That’s why dull scissors sometimes feel like they’re “chewing” instead of cutting. The blades may still be sharp enough. The hit point alignment is just wrong.

How to check yours

Hold your scissors up to a light source and slowly close them. Watch where the blades contact each other. The contact should be a single clean line that progresses smoothly from heel to tip. If the blades gap in the middle, or if contact happens in patches rather than a smooth progression, the hit point geometry needs attention.

This is also something you can feel. Clean hit point contact has a distinct smooth resistance. Uneven contact feels gritty or catchy, almost like the blades are fighting each other.

What affects the hit point

Three main things control your hit point:

Blade tension. Too loose and the blades separate during cutting, missing the hit point entirely. Too tight and they bind. The tension needs to be just right for the blades to ride against each other with consistent pressure.

Blade curvature. Professional scissor blades are slightly curved (not flat). This curve is engineered so that contact happens at a single progressing point. If a blade gets bent from a drop, the curve changes and the hit point goes off.

The ride surface. The tiny bearing area near the pivot (see Ride / Half-Moon) guides the blades. If this surface wears or gets damaged, the blades can wobble, which disrupts the hit point even with correct tension.

What to tell your sharpener

If your scissors are folding hair, tell your sharpener: “The hit point seems off. The blades aren’t contacting cleanly from heel to tip.” This gives them specific diagnostic information instead of a vague complaint. Any skilled sharpener will know exactly what to check.
