Barber Scissor Steel Guide: Grades and Hardness
440C, VG-10, ATS-314 and cobalt alloys, what HRC means, and how much steel should drive the choice.
Quick answer
Most barber scissors are made from one of four steel families. Stainless alloy (56 to 58 HRC) is the training grade, 440C (58 to 61 HRC) the working standard, VG-10 (60 to 62 HRC) the mid to upper range, and ATS-314 cobalt (62 to 63 HRC) premium. Harder steel takes a finer edge, but length, hand and handle matter more.
Steel is the material the blades are made from, and hardness is how hard that steel has been made by heat treatment. Both matter, but less than length, hand and handle. Read this to understand the names on a listing, then go back to the cut you need.

| Steel | Type | Typical HRC on our range | Where it sits | Example |
|---|---|---|---|---|
| Stainless alloy | General stainless | 56 to 58 | Training and apprentice cutters | Ichiro Ergo |
| 440C | High-carbon stainless | 58 to 61 | The working standard | Mina Sakura, Ichiro Offset |
| VG-10 | Stainless with cobalt and vanadium | 60 to 62 | Mid to upper range | Juntetsu Japan Offset |
| V10W | Stainless | 58 to 60 | Upper range | Kasho Balanced Precision |
| ATS-314 | Cobalt stainless | 62 to 63 | Premium | Juntetsu Sword, Yasaka Offset |
Typical HRC comes from our product pages. The diagram below shows the full listed spread for each steel.
What HRC hardness means
HRC is hardness on the Rockwell C scale. A diamond point is pressed into the steel under a set load and the depth sets the number. Higher means harder. Barber scissors usually sit between 56 and 63 HRC.
Hardness comes from heat treatment as well as the steel. The same steel can be finished softer or harder by different makers, which is why one grade shows a range.
What a harder blade changes:
- It can be ground to a finer edge. That suits convex, slicing edges.
- It is less forgiving of drops. Very hard tips are more likely to chip than bend.
- It needs the right sharpening equipment. Ask your sharpener before booking.
440C: the working standard
440C is a high-carbon stainless steel and the most common grade on barber scissors. It takes a good edge, resists corrosion and sharpens without fuss. Yasaka’s material notes describe both its 440C and its ATS-314 as stainless steels from Proterial, formerly Hitachi Metals.
Most Mina and Ichiro cutters use 440C at 58 to 60 HRC. It is the right steel for an apprentice and a sensible one for a working barber’s backup pair.
VG-10 and V10W: the step up
VG-10 is a stainless steel from Takefu Special Steel with cobalt and vanadium added. Takefu’s VG-10 page publishes its composition. In scissors it is usually finished at 60 to 62 HRC, harder than most 440C.
Much of the Juntetsu range, and Ichiro’s Premium Taiyo and Tsuki cutters, use VG-10. Kasho lists V10W on its Balanced Precision cutter.
ATS-314 and cobalt: premium steels
ATS-314 is a cobalt stainless steel used on premium Japanese shears. On our range it is listed at 62 to 63 HRC, the hardest common barber grade. Yasaka uses it across most of its cutters, as do the Juntetsu Sword, Kenshi and Mastersmith lines.
“Cobalt” on its own is not a steel name. ATS-314 and VG-10 both contain cobalt. Joewell’s blade material notes separate its cobalt-base alloy, used on the Joewell Cobalt, from stainless steels that contain cobalt. Joewell also uses a powder metal alloy on the Supreme Symmetric. Read the full name on the listing.
Steel and daily care
Every steel here is a stainless grade, but stainless means it resists rust, not that it cannot mark. Hair, water and product left on any blade will stain it in time, and harder steels are no exception. Wipe and dry after each client, oil the pivot at the end of the day and store the shear in a case.
Hard cobalt steels deserve extra care with drops and with sharpening. Use a sharpener who works on Japanese convex blades. The maintenance guide sets out the routine and the sharpening services guide lists what to ask.
What steel does not decide
A better steel cannot fix the wrong length, hand or handle. It does not set the edge type either: the same VG-10 can be ground convex or bevel. And the maker’s grinding, polishing and pivot work shape the cut as much as the steel.
Country of make is also a separate question. The Japanese vs German scissors comparison covers that. For edge type, read convex vs bevel edge barber shears.
Which steel for you
Apprentice. 440C or stainless alloy, under A$200. Learn the cut before paying for the steel.
Working barber. 440C or VG-10 for the main cutter. VG-10 suits a convex slicing cutter.
Upgrade. ATS-314 for a long sword blade or a convex detail cutter.

Questions
What is the best steel for barber scissors?
There is no single best. 440C is the proven working steel at an accessible price. VG-10 and ATS-314 are harder and take a finer edge, which suits convex slicing cutters. Choose length, hand and handle first, then the steel your budget allows.
What does HRC mean on scissors?
HRC is hardness on the Rockwell C scale, measured by pressing a diamond point into the steel. Barber scissors usually sit between 56 and 63 HRC. Higher means harder.
Is higher HRC always better?
No. Harder steel takes a finer edge, but it is less forgiving if you drop the shear, and it needs the right equipment to sharpen. Edge geometry and the maker's finishing matter as much as the number.
Is 440C good for barber scissors?
Yes. 440C is a high-carbon stainless steel and the most common working grade on barber scissors. It is what most Mina and Ichiro cutters use, at 58 to 60 HRC.
What is cobalt steel in scissors?
Usually a stainless steel with added cobalt, such as ATS-314 or VG-10. Joewell also makes a cobalt-base alloy, which is a different material. Read the full steel name rather than the word cobalt alone.
