Jovvi titanium screwdrivers feature solid Grade 5 Ti blades (not coated, not welded) with tang-through brass handles. Laser marking is applied to both the blade and handle for complete traceability.

Manufacturing Steps:
| Step | Process | Quality Check |
|---|---|---|
| 1 | Swiss-type CNC lathe machines blade from Ti bar | Concentricity <0.05 mm |
| 2 | Tip grinding (Phillips, Torx, or flathead) | Optical comparator (50×) |
| 3 | Heat treatment (age hardening) | Hardness 38–42 HRC |
| 4 | Brass handle casting + machining | Knurling depth check |
| 5 | Blade press-fit into handle (tang-through) | Pull test (500 N) |
| 6 | Laser marking on blade | Permanent mark verification |
| 7 | Laser marking on handle (optional) | Customer identifier |
| 8 | Magnetic susceptibility test | χ < 5 × 10⁻⁶ |
Laser Marking Locations:
Blade: “Ti ≥90%” + size (e.g., “#2”) + batch number – laser-annealed near handle junction
Handle (optional for volume orders): Customer name, asset number, or department code
Example Blade Mark:JOVVI Ti ≥90% | PH2 | BATCH: 2409-01 (for Phillips #2)
Torx Screwdriver Marking:JOVVI Ti ≥90% | T20 | SN: T20-0421
