Serrated Blade Care

Keep serrated shears gripping cleanly with targeted cleaning, tension, and sharpening strategies.

Serration fundamentals

Serrated blades feature micro teeth along one blade to grip hair during blunt cutting. They excel in barbering, men’s grooming, and scissor-over-comb work.

Maintenance routine

  • Clean teeth carefully: Use a soft toothbrush or interdental brush to remove hair fragments before wiping.
  • Avoid aggressive cloths: Microfiber only—rough cloths wear down serrations.
  • Tension sweet spot: Slightly tighter than smooth blades; test regularly to maintain grip.
  • Oil sparingly: Excess oil can trap debris between serrations; wipe thoroughly after application.

Sharpening considerations

  • Only send to sharpeners with serration tooling. Ask how they protect the serrated blade while honing the smooth blade.
  • Expect alternating sharpenings: sometimes only the smooth blade needs work; serrated edges wear slower if handled correctly.

When to replace

  • Teeth feel smooth when tested gently with a fingernail.
  • Hair slips during standard blunt cuts despite proper tension.
  • Serrations show visible chips under magnification.

Document replacements in your maintenance log and budget via the Investment Strategy.

Complementary tools

Pair serrated shears with a polished convex shear so you can switch based on technique, reducing wear on the serrated edge.
