Self-Sharpening Myth

Self-Sharpening Myth

Quick look

• Marketing fiction: No professional shear sharpens itself-blade friction always dulls the edge.¹
• Risk: Waiting for a “self-sharpen” moment forces stylists to cut closer to the fingers, raising injury odds.¹
• Reality: Consistent maintenance with qualified sharpeners keeps performance (and warranties) intact.^1,2

Why stylists should care

Manufacturers occasionally tout self-sharpening edges, but experienced sharpeners agree the claim is a sales hook. Every close rubs metal against metal, wearing the edge and ride line until the shear pushes hair or folds the guide.¹ Planning real service intervals protects your investment and maintains the glide you rely on.²

Technique map

• Educate teams and apprentices about true sharpening schedules so they do not overwork dull blades.¹
• Document usage hours for each shear to anticipate when performance will drop.²
• Budget sharpening into service pricing instead of hoping a mythical feature will cut costs.²

Usage notes

1. Run a weekly tension and sharpness test; if the shear drops shut or folds hair, book service immediately.²
2. Rotate in backup shears so you are never forced to finish a cut with a blunt edge.
3. Ignore freezer, sandpaper, or foil “self-sharpening” hacks-they remove temper and void warranties.¹

Maintenance

• Schedule professional sharpening every 6-12 months (or sooner for heavy users) to keep edges true.^1,2
• Clean, oil, and store shears properly-the basics extend time between services more than any gimmick.²
• Track service history for each tool so you can spot premature wear or technician issues.²
