Technical Manifest

  • OriginGermany
  • MaterialChrome vanadium electric steel, oil-hardened[3]
  • WarrantyLifetime Limited Warranty[1,2]
  • Repairability8/10(LIMITED Parts)[8]
  • "Score 8/10: While the central pivot is a permanent box joint (not user-replaceable), the tool's simplicity means there are no small springs or delicate parts to break. It is 'repairable' in that it can be cleaned of rust and sharpened, but component replacement is not standard."

Financial Verdict

"Forged from chrome vanadium electric steel and oil-hardened. The box-joint design provides high stability due to double guide, preventing the pivot bolt from shearing under load. Teeth are induction hardened to approx. 61 HRC for low wear."
