Sharpener Vetting Checklist
Evaluate professional sharpeners with a 10-point checklist so your shears return factory-perfect every time.
10-point vetting checklist
- Training credentials: Ask for manufacturer certifications or proof of attending recognized shear sharpening programs.
- Equipment inventory: Verify they use flat-hone or convex-hone systems appropriate for hair shears (e.g., Hira-To, Hamaguri wheels).
- Angle documentation: Request before/after angle measurements or photos.
- Service guarantee: Ensure they offer redos if the edge fails within 7–14 days.
- Turnaround time: Confirm realistic timelines; rushed same-day work can signal corner-cutting.
- References: Contact stylists or salons they currently support.
- Liability insurance: Reputable sharpeners carry coverage for tool damage.
- Maintenance advice: They should provide care tips and note any issues spotted.
- Serial logging: Quality partners record serial numbers to track service history.
- Specialty support: Confirm experience with your specialty tools (swivel, notcher, powder steels).
Interview script
Use these questions during your first call or visit:
- “Which brands are you factory-trained on?”
- “How do you protect ride lines on convex shears?”
- “Can you share your process for setting tension before returning tools?”
- “What documentation do you provide after sharpening?”
Warning signs
- Offers to sharpen on grinding wheels meant for knives
- No physical address or professional references
- Refuses to discuss technique or equipment
- Only accepts cash without receipts
Building a preferred vendor list
- Trial at least two sharpeners and compare results.
- Document feedback in a shared spreadsheet (include cost, turnaround, quality score).
- Update the list annually and share with your team or education attendees.
Backup plan
Maintain a backup shear set before shipping tools out. Factor shipping timeouts into your Sharpening Frequency Matrix.
