Read a steel claim as a four-layer record

A grade can be useful evidence, but a finished shear adds maker execution, geometry, condition, and service history.

Description

"Sintered Metal" is material wording used for Kasho Millennium scissors. Review the published description and the composition and performance details not disclosed.

Sintered Metal (焼結金属)

Quick look

  • Published wording: Kasho product material refers to sintered metal for Millennium models.
  • Composition and hardness: Not established by the sources listed on this page.
  • Microstructure and corrosion: Require maker data or suitable testing tied to the finished material.
  • Weight and feel: Depend on the complete model, geometry, size, handle, assembly, and adjustment.

Manufacturing process — powder compaction and sintering

Sintering generally compacts powder and bonds it with heat below the material’s full melting point. That general definition does not prove the exact powder route, pressure, atmosphere, density, grain size, porosity, or manufacturing location used for a Kasho blade. The reviewed product wording should therefore be reported narrowly rather than expanded into an undocumented factory process.

Why it matters

Different powder-metallurgy routes can produce different structures and properties. Without process and test data for this material, this page cannot claim an advantage over a conventional or powder-metallurgy steel, or predict edge consistency in a finished scissor.

Kasho Millennium Series (KML)

Kasho’s published range places the material wording on Millennium Series models. Confirm the exact model, current specification, and manufacturing-origin statement on the official product page.

Shear pairing & edge compatibility

  • Kasho Millennium models: Confirm the published material and edge geometry for the exact size and version.
  • Other tools: Do not infer cross-brand use or compatibility from the general term.

Technique map

  • Match the exact model’s size, geometry, and handle to the intended technique.
  • Compare fit and cutting behavior in a safe, relevant trial.
  • Treat brand reputation, regional heritage, and price as context rather than performance measurements.

Performance evidence

No universal edge-life, toughness, impact, balance, or feel claim follows from the material wording. Those comparisons require disclosed composition and process information, finished-model samples, a defined method, and relevant conditions.

Maintenance notes

Follow the current maker instructions for cleaning, oiling, storage, adjustment, sharpening, warranty, and service. Ask the official service contact about the exact model rather than selecting a process from a presumed microstructure.

Industry snapshot

  • Kasho / KAI Corporation (貝印): The reviewed sources associate the wording with Millennium models. They do not establish exclusivity, full in-house process control, or every manufacturing location.

Trade-offs

  • The listed sources do not provide a complete composition or finished hardness, limiting comparison.
  • The material wording alone does not establish exclusivity, edge life, origin, or value.
  • Compare the complete model, price, fit, seller terms, warranty, and service route.

Quick clarifications

Frequently Asked Questions

3 answers you can open one at a time
What type of material is Sintered Metal (Kasho)?

Kasho uses the wording for Millennium models, but this page has no complete composition, finished-hardness range, microstructural report, or comparative performance test. Use current model documentation for disclosed specifications and leave other properties unresolved.

How is servicing handled for scissors made from Sintered Metal (Kasho)?

Check the exact model’s current care, sharpening, warranty, and authorized-service instructions. The phrase alone does not determine an interval, geometry, equipment, or technician credential.

Which scissor brands and cutting styles use Sintered Metal (Kasho)?

The sources reviewed here tie the wording to Kasho Millennium models. Do not extend it to another brand, assume an in-house alloy, or infer a cutting style without a source for the exact model.
