- WarrantyLimited Lifetime Warranty[1,2]
- Repairability1/10[8]

Failure Threat Matrix[5,6,7]
| Failure Mode | Likelihood | Est. Onset | Mitigation Strategy |
|---|---|---|---|
| Grip delamination | Medium (High usage) | Random | Store out of direct sunlight (UV degrades rubber). Avoid exposure to solvents. |
| Surface Rust | High (if neglected) | Random | Keep dry and lightly oiled. Remove rust with steel wool. |
| Magnet loss | Low | Random | None (glued component). Verify magnet security before purchase. |
