Technical Manifest
- OriginUSA
- MaterialOne-piece forged solid steel, genuine leather grip[3]
- WarrantyLimited lifetime warranty[1,2]
- Repairability3/10[8]
- "Score 3/10: The one-piece steel design makes the handle structural and non-replaceable by average users. However, this design eliminates the most common hammer failure (broken handle). Leather grip restoration is possible but requires craft skills."
