Checking & Maintaining Knives and Daggers

1. The Need for Regular Inspection

  • Inspect every knife or dagger before each rehearsal and performance.
  • Reinspect it after any drop, unusually hard contact, or other possible damage.
  • A prop that was previously fight-worthy may no longer be so.

2. Blade

Check for:

  • Bends, cracks, or other distortion
  • Burrs, nicks, or newly sharpened areas along the edges
  • Damage or deformation at the point
  • Corrosion or deep pitting
  • Movement where the blade enters the handle or guard

3. Handle and Fittings

Check for:

  • A loose handle or grip
  • A shifting guard
  • A loose pommel or butt
  • Cracked, split, or damaged handle material
  • Sharp projections, exposed fasteners, or loosened decorative pieces

For folding knives, also check the pivot, lock, and blade movement.

4. Sheaths

  • Make certain the sheath fits securely without gripping the blade too tightly.
  • Check for exposed fasteners, damaged seams, or anything that may scratch the actor or catch on the costume.
  • Confirm that the knife can be drawn and returned safely as required by the staging.

5. Cleaning and Maintenance

  • Remove moisture, fingerprints, dirt, stage blood, and other residues after use.
  • Protect steel blades from rust with a light coating of oil when appropriate.
  • Keep oil away from handles, costumes, and areas the actor must grasp.
  • Tighten loose components only when the construction and correct method are understood.
  • Do not disguise cracks or structural damage with cosmetic repairs.

6. Damage and Retirement

  • Remove any questionable prop from use immediately.
  • Do not continue using it merely because no replacement is available.
  • Repairs affecting the blade, tang, handle, lock, or other structural components should be made by someone qualified.
  • Retire any knife or dagger that cannot be restored confidently to fight-worthy condition.
