A high-carbon chromium stainless grade used in different cutting and texturising models.
440C is a high-carbon chromium stainless steel. Carpenter Technology’s 440C sheet gives a typical result of about HRC 60 after heat treatment. That describes its material, not a hardness measurement or cutting test for every finished scissor labelled 440C.
| Maker and model | Maker-published detail | What the detail tells you |
|---|---|---|
| Yasaka YA-5.5 | SUS440C blade material; 141 mm overall and 58 mm blade length; offset handle | A named cutting scissor with a stated material and dimensions. |
| KAI USA Kasho Design Master KDMT38 | The US listing specifies 440C steel; 6.0-inch, 38-tooth blender; ratchet flat-head pivot | A named US catalogue texturizer, not a specification for every Design Master. |
The two examples share a steel label but differ in use, blade design, size and handle. Check the market sheet: Kasho Europe’s Design Master page describes the series, including texturizers, as VG-10W. The regional pages do not reconcile this difference for a particular pair. Ask the seller to confirm the exact model and blade material rather than treating the US KDMT38 listing as a range-wide rule.
Neither maker publishes a universal 440C sharpening interval on these sheets. A dropped edge can chip, and stainless steel still needs cleaning and drying; Yasaka’s care guidance explicitly warns about both impact and corrosion.
Start with the cutting or blending task, then compare the exact model’s blade length, edge, handle and hand orientation. Ask the seller or maker who can service that edge in your market and what the current terms are. If a seller quotes HRC, ask whether it is measured for the finished model or drawn from a general alloy description.
For another material name, see VG-10 and ATS-314. The Yasaka and Kasho profiles provide more model context.
