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."
The Comparison Standard
Financial Verdict
"Requires only occasional cleaning and a drop of light machine oil on the joint. No consumables required."
