Tension Washers
Description
Tension washers sit at the pivot to maintain consistent blade pressure and smooth action. Learn about washer materials, replacement signs, and their effect on cutting feel.
Tension Washers (パッキン / テンションワッシャー)
Quick look
- What it is: Thin discs or rings seated between the blade and the tension screw assembly at the pivot
- Purpose: Control friction, smoothness, and long-term tension stability
- Types: Flat/plain washers (パッキン), clicker plates, rubber O-rings
- Maintenance: Should be inspected during every professional service
Why it matters
Tension washers sit at the heart of the pivot assembly, quietly governing how your scissors feel every time you close them. They are small, inexpensive parts that have an outsized effect on cutting quality.
Flat / plain washers (パッキン, pakkin): The most basic type. A simple disc that provides consistent friction between the blade and the pivot hardware. Found in the majority of scissors across all price points. Reliable and easy to replace, but offers no mechanical feedback.
Clicker plates: Ratchet-style washers with notched surfaces that produce a tactile click at each tension increment. These give the stylist repeatable tension settings, making it easy to return to a preferred position after cleaning or adjustment. Common in mid-range and premium scissors.
Rubber O-rings: Soft rings that provide cushioning at the pivot. They absorb micro-vibrations during cutting and add a smooth, dampened feel to the blade action. More prone to compression and wear than metal washers, so they need replacement more frequently.
Washer quality directly affects how long your tension setting holds. Cheap washers compress, deform, or wear unevenly, causing the tension to drift within days of adjustment. Quality washers from reputable manufacturers maintain their profile for months. When tension starts drifting faster than it used to, worn washers are often the cause.
Have your sharpener inspect washers during every professional service. They are consumable parts and should be replaced before they compromise the feel of an otherwise well-maintained scissors.
