Short answer: for most stylists and barbers, a 5.5″ or 6″ hardened stainless steel shear with a convex (razor) edge, an offset handle and an adjustable tension screw is the best all-round choice. Barbers who do a lot of scissor-over-comb often add a longer 6.5–7″ shear.
1. Length: 5″ to 7″
Shear length is measured from the tip of the blade to the end of the longest finger ring (not counting the finger rest).
| Length | Best for |
|---|---|
| 5″–5.5″ | Precision work, detailing, smaller hands |
| 6″ | All-round cutting — the most popular size |
| 6.5″–7″ | Scissor-over-comb, barbering, longer sections |
A quick fit test: lay the shear on your open palm. The blade should be roughly the length of your middle finger.
2. Steel and hardness
Good shears are made from hardened stainless steel. Harder steel holds a sharper edge for longer; softer steel is easier to resharpen but dulls faster. Look for shears that are heat-treated and hand-honed, and avoid unbranded shears that feel light and flex when closed.
3. Blade edge: convex vs bevelled
- Convex (razor) edge: extremely sharp and smooth, ideal for slide cutting and point cutting.
- Bevelled edge: slightly less sharp but very durable, often with a micro-serration that grips hair — popular for blunt cutting and beginners.
- SuperCut / serrated blade: one blade has fine serrations that stop hair sliding forward; a good choice for students. See our SuperCut and barracuda scissors.
4. Handle style
- Opposing (classic): symmetrical rings — traditional, good for barbers who rotate the shear.
- Offset: shorter thumb ring keeps the thumb in a more natural position and reduces strain.
- Crane: strongly offset — the most ergonomic for long days, lets you keep your elbow down.
- Swivel thumb: rotating thumb ring for stylists with wrist or thumb pain.
Left-handed stylists need true left-handed shears, where the blades are reversed — not just a right-handed shear held upside down.
5. Tension screw
An adjustable tension screw lets you set how freely the blades move. Test it: hold the shear by the thumb ring with the blade pointing up, open it to 90° and let go of the finger ring. The blade should fall about two-thirds of the way closed. If it falls fully closed, tighten; if it barely moves, loosen.
How to hold barber scissors correctly
- Put your ring finger (not your middle finger) through the finger ring, up to the first knuckle.
- Rest your little finger on the finger rest (tang).
- Place only the tip of your thumb in the thumb ring.
- Keep the index and middle fingers on the shank to steady the shear.
- Move only the thumb when cutting — the still blade stays steady, which gives straighter, more accurate lines.
When combing, “palm” the shears: slip your thumb out and close the shear into your palm so you can hold the comb safely.
Care that doubles shear life
- Wipe and dry the blades after every client; hair products and water cause corrosion.
- Oil the pivot weekly and close the shear when not in use.
- Never cut paper, thread or plastic with hair shears.
- Store them in a case — one drop on a tile floor can bend a tip.
Frequently asked questions
What size scissors do barbers use?
Most barbers use a 6″ shear for general work and a 6.5″–7″ shear for scissor-over-comb, plus a thinning or blending shear.
Are expensive shears worth it?
Price follows the steel, edge and hand-finishing. A well-made mid-range shear that is hand-honed will outperform a cheap pair for years; you do not need the most expensive model to start.
How often should shears be sharpened?
With daily professional use, roughly every 6–12 months. Keep them clean and oiled and only send them to a specialist sharpener who handles convex edges.
Can I buy shears with my salon name engraved?
Yes — we laser-engrave names and logos on shears and nippers from a single piece. See the customization page.
