Technical Manifest
- OriginChina
- MaterialTempered steel and die-cast metal
- Warranty5-Year Limited Warranty
- Repairability2/10
- "Score 2/10: Disposable tool. While the locking nut and scratch awl are physically removable, the manufacturer does not sell replacement parts. Once the true 90-degree angle is lost or the locking thread is stripped, the item cannot be practically recalibrated or repaired."
The Comparison Standard
Financial Verdict
"Requires periodic oiling (3-in-1 or M1 oil) and light cleaning with steel wool to prevent rust on the blade. Estimated at $5/year for consumables."
Failure Threat Matrix[1,2,3]
| Failure Mode | Likelihood | Est. Onset | Mitigation Strategy |
|---|---|---|---|
| Loss of true 90-degree squareness | High | Random | Avoid dropping the tool. Verify accuracy periodically against a known 90-degree reference point. |
| Surface rust on blade | Medium | Random | Wipe down the blade with an oiled cloth after each use. Store in a dry environment. |
| Stripped locking nut | Medium | Random | Avoid overtightening the brass/metal locking nut. |
