Convex Edge Hairdressing Scissors

Where convex shines

• Dry detailing: Clean up shattered lobs, mullets and curly shapes without frizzing the ends.
• Slide and point cutting: The polished inner ride lets you carve texture with zero snagging.
• Precision bobs: Keeps perimeter lines glassy so you do not have to cross-check three times.
• Advanced barbering: Ideal for scissor-over-comb when you need micro control around ears and hairlines.

Choose the right fit

• Steel: Look for Japanese cobalt alloys (ATS-314, VG-10) or powdered steel for edge retention.
• Size: 5.5" for precision and dry work; 6" if you want balance between control and speed.
• Handle: Offset or crane to keep your elbow low during detail passes; avoid straight handles unless you have bulletproof wrists.
• Tension dial: Convex blades bruise easily, so pick a click-dial you can set without over-tightening.

When to be careful

Convex scissors are unforgiving if you drop them or send them to the wrong sharpener. They also expose sloppy technique—any over-twisting in your thumb drives micro-nicks into the edge. If your salon shares tools, keep these in a case with your name on it.

Maintenance drill

1. Clean with a soft cloth after each client, especially if you are cutting dry product-laden hair.
2. Oil the pivot nightly using a single drop of lightweight scissor oil.
3. Run a weekly tension check with the drop test—convex blades hate being slammed shut.
4. Book professional convex sharpening only. Ask for waterstone finishing or a Japanese master sharpener. No bench grinders, ever.
