Bumper / Silencer

Bumper / Silencer (ゴム / サイレンサー)

Quick look

  • What it is: A small rubber or plastic cushion between the finger rings
  • Purpose: Absorbs impact when scissors open fully, reduces noise, controls opening angle
  • Lifespan: Consumable part that wears out and needs periodic replacement
  • Cost: Very inexpensive, usually a few dollars for a pack of replacements

Why it matters

The bumper is one of those parts you never think about until it falls off. Then suddenly your scissors are louder, the blades over-extend on every stroke, and the whole feel changes. It’s a small piece of rubber that sits between your finger rings and cushions the stop when your scissors reach full open position.

When a bumper wears out or goes missing, the metal-on-metal contact between the rings can damage the scissors over time and contributes to hand fatigue from the constant jarring. Keep a few spares in your kit. They cost almost nothing and take seconds to replace.
