A cobalt-based material family; Mizutani lists it on named cutters and thinners.
Stellite covers a family of cobalt-based alloys. Kennametal Stellite’s catalogue lists several formulations with different hardness and wear properties. Its industrial alloy data cannot be assigned to a finished hair scissor without the maker’s model specification.
| Model | Maker-published material and use | Buyer check |
|---|---|---|
| Stellite alloy 555 | Mizutani lists a 5.5-inch all-round cutting model in its Stellite series. | Compare length, edge and handle with your cutting work. |
| Stellite alloy 531 Staygold | Mizutani describes a reverse-blade thinner, a 64 mm blade and a stated 25–30% cut rate. | Decide whether that removal rate and orientation fit your technique. |
Mizutani calls its Stellite material rust-free and describes its durability, but the model pages above do not provide a verified 3,000-cut sharpening interval, a non-magnetic test or a comparison proving a longer edge life than every other alloy. Stellite’s name alone also does not tell you whether you need a cutter or a thinner.
Mizutani’s manual still tells owners to wipe off water, colour and perm solutions and to ask for factory sharpening if basic checks do not restore cutting. Ask a seller what local service is available for the exact model, what it costs and which terms apply. A corrosion-resistant material does not remove the need to clean, dry and maintain the complete scissor.
For other named Mizutani materials, see the brand profile and the cobalt-alloy guide. Compare the model’s task, hand fit and service support before paying for a material label.
