Inner Hollow / Concave
Inner Hollow / Concave
Quick look
- Friction control: Hollow grinding removes metal behind the edge so blades touch lightly and close without crushing hair.1,2
- Edge support: A polished ride line keeps the razor edge aligned and extends service life.1,2
- Service needs: Poor sharpening that flattens the hollow destroys glide and the shear’s bite.1,2
Why stylists pick it
Every premium convex or semi-convex shear relies on the inner hollow. By carving relief into the interior face, manufacturers ensure only the edge and ride line make contact, which produces the smooth, silent close stylists associate with high-end tools.1,2
Technique map
- Any technique that depends on low resistance-dry detailing, slide work, and point cutting.1
- Supporting daily salon rotations by keeping the edge sharp longer between services.2
- Ensuring tight, even closure during precision barbering work.2
Usage notes
- Perform regular tension tests; a loose pivot lets the hollowed blades chatter and nick the ride line.2
- Keep the interior spotless-lint or hardened product defeats the low-friction design.1
- Avoid tapping blades together or laying them open; protect the ride line from flat surfaces.2
Maintenance
- Choose sharpeners who re-establish the ride line and hollow on specialty stones rather than bench grinders.1,2
- Oil sparingly along the ride line so the edge closes smoothly without attracting debris.1
- Schedule service before the edge feels dull; excessive force can overheat and warp the hollow.2
