Static Blade

Static Blade (静刃, Seiba)

Quick look

Position: Ring finger side
Function: Provides the fixed reference surface for cutting
Wear rate: Slower than the moving blade
Japanese term: 静刃 (seiba, literally “still blade”)

Why it matters

The static blade is the one held by your ring finger. During a normal cut, it stays relatively stationary while the moving blade (thumb side) does the work of closing against it. Think of it as the anvil while the moving blade is the hammer.

Because it moves less, the static blade experiences less friction and wears more slowly than its counterpart. This is why you might notice one blade staying sharper than the other over time. That’s normal and expected.

The distinction matters for sharpening

A skilled sharpener will often treat the two blades slightly differently during service, accounting for their different wear patterns. The static blade may need less material removed. Telling your sharpener which blade feels duller gives them useful information.

Proper technique

In Japanese scissor training, understanding which blade is which is considered a foundational skill. Beginners are taught to keep the static blade still and only move the thumb. Opening the scissors by pulling the ring finger down (moving the static blade) is a common bad habit that leads to uneven cuts and faster wear on both blades.
