Top 10 Hair Scissor Terms That Are Easy to Mix Up

Most scissor confusion comes from two words that sound alike but describe different things. These ten pairs are the ones that cost people the most time on a listing, a course kit list or a salon floor.

1. Scissor size and blade length

Size is the maker’s inch label for the whole scissor, from the end of the rings to the tip. Blade length is the working part, from the pivot to the tip. A 5.5” pair has a shorter blade than that, and makers measure differently, so compare like with like. Yasaka’s SA-5.5 page, for example, lists a 60 mm blade for the 5.5”. Our size guide shows how to measure both.

Why it matters: two 5.5” pairs from different makers can have different blade lengths, so the size alone won’t tell you which one reaches further.

2. Grind, shape and finish

Three words get used as if they were one. The grind is how the edge is ground, such as convex or bevelled. The shape is the outline of the blade, such as straight, curved or sword. The finish is the surface, such as smooth or micro-serrated. A listing can combine any of them, so don’t compare “convex” with “sword”. See the convex edge guide for more.

Why it matters: a convex edge doesn’t guarantee slide cutting. The use the maker describes for the model is the better guide.

3. Offset, crane and swivel

These describe the handle. Offset makes the thumb branch shorter, so the thumb ring sits closer to the pivot. Crane bends the handle further. Swivel means a ring that rotates. None of them changes the blade, and none is a treatment for sore hands. Our swivel hair scissors page lists the rotating pairs.

Why it matters: the handle changes where your thumb sits, and a new layout feels different for a while. The blade still cuts the way it was ground.

4. Left-handed and left-hand-friendly

A true left-handed pair has its blades reversed for the left hand, as well as the handle. A pair that’s left-hand-friendly or has symmetric rings can be held in either hand but still has right-handed blades. A mirrored product photo doesn’t tell you which you’re buying, so check the hand in the selector. Our left-handed guide explains why it matters.

Why it matters: the blade orientation changes what you can see along the blade as you cut, and a right-handed pair held in the left hand can’t be turned into a true left-handed one.

5. Tooth count and cut ratio

Tooth count is how many teeth a thinner has. Cut ratio is the maker’s estimate of how much of a section one close removes. Joewell’s E-40 and SNT-40 both have 40 teeth, but Joewell lists them at 35% and about 5% or less. Where there’s no ratio, ask rather than guess. Our cut ratio guide has the figures.

Why it matters: start lighter than you think. A second pass is easy, and a heavy first pass can’t be undone.

6. Thinner, blender, texturiser and chunker

Brands overlap these labels, so read the teeth and the ratio, not just the name. As a rule of thumb, a thinner or blender has many fine teeth to soften weight, a texturiser has fewer, wider teeth for visible texture and a chunker takes out bold, broken pieces.

Why it matters: choose by the job. Blend once the outline is cut, and texturise once the shape is set.

7. Tension and sharpness

Tension is how much resistance the pivot gives as the blades close. Sharpness is the condition of the edge. Loose tension can fold hair on a sharp pair, and over-tightening can’t rescue a worn edge. Check tension the way your maker says to, as set out in our dragging scissors guide.

Why it matters: loosening to feel smoother and tightening until the folding stops are both fixes for the wrong problem.

8. Sharpening and servicing

Sharpening restores the edge. Servicing is wider: it can include an edge, a nick, the alignment, the pivot and the bumper. A pair that clicks after a drop probably needs servicing, not just a sharpen. Tell the technician what changed and when. Our sharpening service page explains what to send.

Why it matters: a note of what went away and what came back makes the next service easier. The maintenance log shows what to write down.

9. Blunt cut and blunt scissors

A blunt cut is a technique: closing straight across a section to set a clean line. Blunt scissors are dull ones. The two have nothing to do with each other, and a dull pair makes a poor blunt cut. Our cutting technique guide covers the moves.

Why it matters: write “blunt cut” or “dull scissors” and nobody on the team has to guess which one you mean.

10. Steel grade, brand and where it’s made

A steel grade, such as 440C or VG-10, names the material. A brand names the company, and origin says where a model is made. They don’t follow each other. For example, Kamisori is a Canadian brand with Japanese-inspired designs, and some models are made in Japan. Check the product page for each fact. The steel library explains the grades.

Why it matters: a grade or a national identity isn’t a score for the scissors. Fit, geometry and care decide how a pair feels in a working day.

Offset, crane, swivel	Handle layouts
