Technical Manifest
- OriginChina
- MaterialDie-cast Zinc Alloy, Physical Vapor Deposition (PVD) Coating[3]
- Warranty100-Year Limited Warranty[1,2]
- Repairability2/10(GOOD Parts)[9]
- "Score 2/10: The razor is a single integrated unit. The tension spring is internal and not accessible without destroying the housing. However, the device requires no maintenance other than cleaning and blade changes."
The Comparison Standard
Financial Verdict
"Requires replacement injector blades. Supply recommends changing blades every 8-10 shaves. Cleaning involves simple rinsing."

Failure Threat Matrix[5,6,7,8]
| Failure Mode | Likelihood | Est. Onset | Mitigation Strategy |
|---|---|---|---|
| Brittle Fracture | Low (requires drop) | Random | Do not drop on hard surfaces (tile/granite). Use a grip sleeve or stand. |
| Spring Fatigue | Very Low | Random | Covered by lifetime warranty. No user mitigation available. |
| PVD Coating Wear | Low | Random | Clean regularly to prevent soap scum buildup which can look like wear. |

Audit Evidence Ledger
High Fidelity: Verified by >5 independent data sources.
- [1]supply.co..."Manufacturer offers 100-year warranty on structural defects"
- [2]amazon.com..."Reviews indicate construction is heavy and solid, expected to last indefinitely if not dropped"
- [3]supply.co..."Product page specifies Die-Cast Zinc Alloy construction with PVD coating"
"Maintenance cost calculated using Supply brand blades ($6/pack). Costs can be reduced to ~$12/year by using generic Personna injector blades ($15 for 20 blades). Repairability is low because the device is a single unit; however, warranty coverage is high."
