440C vs VG-10 vs ATS-314: Budget to Mid-Range Steel Compared
If you have been researching professional scissors for more than fifteen minutes, you have encountered three steel names: 440C, VG-10, and ATS-314. They appear on spec sheets, in marketing copy, and in every online forum debate about which scissors to buy.
The problem is that most comparisons either oversimplify (“VG-10 is better than 440C”) or drown you in metallurgical data that means nothing to someone who just wants to know which steel is worth their money. Here is the practical comparison, focused on what each steel actually means for your cutting, your maintenance schedule, and your budget.
The Three Steels at a Glance
| Property | 440C | VG-10 | ATS-314 |

These numbers matter, but only if you understand what each element actually does in a scissor blade. Let us break that down.
440C: The Reliable Workhorse
What It Is
440C is a high-carbon, high-chromium martensitic stainless steel. It has been the global standard for professional scissors since the 1970s and remains the most widely used scissor steel in the world. The “440” family includes 440A, 440B, and 440C, with 440C having the highest carbon content and therefore the best edge retention of the group.
Why It Works
The high chromium content (16-18%) gives 440C outstanding corrosion resistance. For a tool that contacts water, chemicals, and hair products all day, this matters. Chromium forms a passive oxide layer on the blade surface that resists rust and chemical staining.
The carbon content (0.95-1.20%) allows 440C to reach 58-60 HRC through conventional heat treatment. This is hard enough to hold a professional edge for months but soft enough that most competent sharpeners can service it without specialist equipment.
Who Uses It
440C appears across the entire price spectrum. German manufacturers like Jaguar have built their reputation on precision-crafted 440C scissors that deliver consistent performance at accessible prices. Cricket uses 440C across much of their range. Budget-friendly professional lines from brands like Mina use 440C to deliver genuine professional performance under $200.
The quality variation within 440C scissors is enormous. A $80 440C scissor from an unknown brand and a $300 440C scissor from an established manufacturer use the same base steel, but the heat treatment, grinding, finishing, and quality control are completely different. The steel is only one variable.
The Limitations
440C lacks vanadium and cobalt, two elements that refine grain structure and increase hot hardness. This means 440C cannot achieve the ultra-fine edge that VG-10 and ATS-314 can reach. For most blunt cutting and point cutting, you will never notice. For slide cutting and razor-like precision work, the difference becomes apparent.
440C also dulls faster under heavy use. A high-volume stylist doing 30+ clients per week will notice the edge deterioration sooner than with harder steels.
VG-10: The Precision Standard
What It Is
VG-10 (V Gold No. 10) is a high-carbon stainless steel developed by Takefu Special Steel in Fukui Prefecture, Japan. The “V” designates vanadium content. It was originally developed for high-end kitchen knives and was adopted by the scissor industry in the 1980s.
Why It Works
VG-10 adds three elements that 440C lacks: vanadium, significant cobalt, and higher molybdenum.
Vanadium (0.10-0.30%) creates very small, hard vanadium carbide particles within the steel matrix. These particles refine the grain structure, allowing the blade to take a finer, more acute edge. This is the main reason VG-10 scissors feel sharper out of the box than 440C scissors.
Cobalt (1.50%) increases the steel’s hardness and heat resistance. It allows VG-10 to reach 60-62 HRC while maintaining enough toughness to resist chipping under normal use. The higher hardness means the edge deforms less during cutting, which translates to longer edge retention.
Molybdenum (0.90-1.20%) improves toughness and prevents a type of corrosion called pitting. It also helps the steel respond to heat treatment more predictably, which reduces manufacturing rejects and improves consistency.
Who Uses It
VG-10 is the dominant mid-range steel in the Japanese scissor industry. Kasho (KAI Corporation) uses VG-10 across significant portions of their range. Juntetsu offers VG-10 scissors from approximately $250 to $500, making it one of the more accessible ways to experience this steel. Yasaka, Joewell, and many other Seki City manufacturers use VG-10 as their primary mid-range steel.
The Limitations
VG-10 is harder than 440C, which means it is also more brittle. Dropping VG-10 scissors on a hard floor is more likely to chip the blade than dropping 440C scissors. The harder steel also requires a sharpener who understands Japanese convex edge geometry – sending VG-10 scissors to a generalist sharpener risks flattening the hamaguri grind and degrading performance.
The lower chromium content (14.5-15.5% versus 440C’s 16-18%) means VG-10 is slightly less resistant to corrosion. In practice, this rarely matters if you maintain your scissors properly. If you leave them wet in a case overnight, VG-10 will show it sooner than 440C.
ATS-314: The Edge Retention Champion
What It Is
ATS-314 is a high-carbon stainless steel produced by Hitachi Metals (now Proterial) in Japan. It is less well known outside the scissor industry than VG-10 but is widely respected among manufacturers who prioritise edge retention and hardness.
Why It Works
ATS-314 pushes the molybdenum content higher than VG-10 (1.00-1.30% versus 0.90-1.20%) while maintaining similar vanadium and cobalt levels. The higher molybdenum increases the steel’s resistance to softening during heat treatment and improves its ability to form fine, hard carbide structures.
The result is a steel that reaches 61-63 HRC – the hardest of the three steels compared here – while maintaining reasonable toughness. ATS-314 holds an edge measurably longer than VG-10 under identical conditions.
Who Uses It
Yasaka is the brand most closely associated with ATS-314. They have refined their heat treatment processes around this specific steel over decades and produce some of the best ATS-314 scissors available. Several other Seki City manufacturers use ATS-314 for their upper-mid-range lines, positioning it between VG-10 and cobalt alloy in their product hierarchies.
The Limitations
ATS-314 has the lowest chromium content of the three steels (13-14.5%). While still technically stainless (the threshold is 10.5-13% chromium, depending on the standard), ATS-314 sits closer to the line. It requires more diligent maintenance than either 440C or VG-10.
The higher hardness also means ATS-314 is the most brittle of the three and the most demanding to sharpen properly. A sharpener who works primarily with 440C may struggle with ATS-314 because the steel resists material removal more aggressively and requires different abrasive strategies.
Practical Comparison: What You Will Actually Notice
Initial Sharpness
ATS-314 and VG-10 can both achieve finer edges than 440C due to their refined grain structure. Between VG-10 and ATS-314, the difference in initial sharpness is negligible – both can achieve a razor-like edge. The real difference is in what happens next.
Edge Retention Over Time
Here is a realistic timeline for a stylist doing 20-25 clients per week, cutting a mix of hair types:
| Timeline | 440C | VG-10 | ATS-314 |
|---|---|---|---|
| Month 1-3 | Sharp | Sharp | Sharp |
| Month 4-6 | Noticeable dulling | Still sharp | Still sharp |
| Month 6-9 | Needs sharpening | Beginning to dull | Slight dulling |
| Month 9-12 | Overdue | Needs sharpening | Beginning to dull |
| Month 12-14 | Well overdue | Overdue | Needs sharpening |
These are general patterns. Your actual experience depends on hair types (coarse and chemically treated hair accelerates dulling), technique (slide cutting wears edges faster), and maintenance (daily cleaning and oiling makes a significant difference).
Maintenance and Sharpening
| Factor | 440C | VG-10 | ATS-314 |
|---|---|---|---|
| Sharpening difficulty | Easy to moderate | Moderate | Difficult |
| Sharpener requirements | Any competent professional | Japanese edge specialist preferred | Japanese edge specialist required |
| Sharpening cost | $25-$50 | $40-$75 | $50-$85 |
| Annual sharpening cost (est.) | $50-$100 | $40-$75 | $50-$85 |
| Corrosion risk | Low | Moderate | Moderate to high |
Notice that annual sharpening costs are similar across all three steels because the harder steels need less frequent service. The per-sharpening cost is higher for harder steels but the frequency is lower.
Cost of Ownership
The true cost comparison is not the sticker price. It is the purchase price plus sharpening costs over the life of the scissors.
| Factor | 440C | VG-10 | ATS-314 |
|---|---|---|---|
| Typical purchase price | $150-$300 | $300-$500 | $350-$600 |
| Annual sharpening | $75 (2x) | $55 (1x) | $65 (1x) |
| 5-year total cost | $525-$675 | $575-$775 | $675-$925 |
| Cost per month | $9-$11 | $10-$13 | $11-$15 |
When you amortise the cost over five years of professional use, the monthly difference between 440C and ATS-314 is roughly $2-$4. The question is not whether you can afford the better steel. It is whether the performance difference justifies even that small premium for your specific work.
