Snapshot
ATS-314 (also written ATS314) is a cobalt-enriched stainless steel produced by Hitachi/Proterial for high-end cutting tools. Public steel references (including ScissorPedia and retailer material guides) position it as a flagship alloy because the fine carbide structure supports exceptionally smooth convex edges.
| Property | Summary |
|---|---|
| Hardness window | Commonly cited around 61–64 HRC after vacuum hardening |
| Edge character | “Glassy” glide suited to slide and point work |
| Corrosion profile | Premium stainless behaviour—resists salon chemicals when wiped down promptly |
| Typical placement | Professional and premium Japanese shears, especially 5.5–6.0” cutters and matched blenders |

Why stylists choose ATS-314
Controlled glide for technical work
Stylists describe ATS-314 edges as smooth and low-drag, which helps during dry detailing, precision bobs, and interior channeling. The alloy’s cobalt and molybdenum content keeps the edge crisp deeper into long colour-correction days than mid-tier alternatives like 440C. (ScissorPedia highlights slide and point cutting as primary use cases.)
Consistent feel across matched sets
Many Japanese manufacturers pair ATS-314 cutters with compatible thinning shears. Maintaining the same alloy front-to-back ensures tension adjustments and wear patterns remain predictable, which is valuable in busy teams or education settings.
Balanced weight
Public steel guides describe the forged blanks as medium-light. In practice, ATS-314 shears tend to feel neutral in hand—enough substance to support long strokes without overloading the thumb.
Technique map
Use ATS-314 when you need:
- Slide cutting without drag: The alloy keeps convex edges polished, helping sections glide smoothly.
- Point detailing and fringe refinement: Fine carbides let tips stay sharp for intricate work.
- Dry texturising: High-tooth blenders made from ATS-314 stay crisp, reducing the risk of hair snagging.
- Long-form education: Educators appreciate the predictable close when demonstrating slow-motion cuts.
For heavy scissor-over-comb or blunt club cutting on coarse hair, you may still prefer a beveled 440C workhorse to absorb repeated comb contact.
Maintenance expectations (public guidance)
- Daily care: Wipe and oil after each shift. Chemical services can leave residue that dulls even premium stainless steels.
- Tension checks: ScissorPedia notes that cobalt-rich steels punish over-tight pivots. Run the drop test weekly to keep the action neutral.
- Sharpening cadence: Our internal steel guide places ATS-314 in the 6–9 month service window for full-time stylists. Confirm the cadence with your sharpening partner.
- Service partner: Choose technicians experienced with Japanese convex edges. Improper grinding can damage the micro-carbide structure.
How it compares
| Steel | Edge life (pro use) | Feel | Typical tier |
|---|---|---|---|
| ATS-314 | 6–9 months | Silky glide, rigid edge | Professional / Premium |
| VG-10 | 6–9 months | Smooth with slightly softer feedback | Upper value / Professional |
| 440C | 4–6 months | Firm, forgiving bite | Value / Entry professional |
For a deeper comparison between VG-10 and 440C, read the VG-10 vs 440C guide and the core VG-10 steel overview. When you’re weighing the next upgrade tier, use the ATS-314 vs ZA-18 comparison to match alloy behaviour with your service mix. Premium cobalt or powder-metal blends (e.g., Mizutani’s proprietary alloys) may extend edge life further but come at a higher price.
Questions to ask before you buy
- Which techniques dominate your week? If slide and detail work make up most of your column, ATS-314 can justify the spend.
- Do you have a trusted convex specialist? Ensure your maintenance partner is comfortable polishing ATS-314 edges.
- Will you run a mixed toolkit? Pair ATS-314 cutters with matching thinners so tension and weight stay consistent.
- How often do you travel? Carry padded cases—public steel notes mention the alloy is rigid and can micro-chip if dropped.
- What does the brand disclose? Review manufacturer or retailer specifications for HRC ranges, handle designs, and warranty terms.
