  • MaterialForged High Carbon U.S. Steel, Vinyl grip coating[3]
  • WarrantyLimited Lifetime Warranty[1,2]
  • Repairability5/10(LIMITED Parts)[9]
  • "Score 5/10: While the steel is virtually unbreakable, the main pivot uses a 'Permalock' rivet that cannot be tightened or replaced by the user if it eventually wears loose. Grips can be re-glued."

Failure Threat Matrix[5,6,7,8]

Failure ModeLikelihoodEst. OnsetMitigation Strategy
Surface RustMedium (if neglected)Random
Keep dry and oiled. Reversible with steel wool or Evapo-Rust.
Grip SlippageMediumRandom
Re-adhere with adhesive or hairspray trick; cosmetic issue only.
Teeth WearLow (requires decades)Random
Clean teeth with wire brush to maintain grip. Sharpening is difficult due to laser hardening.
