Compare Mizutani's named material with other powder steels by exact model and cutting task.
Powder metallurgy describes a way of making a material; it does not name one finished hair-scissor grade. Takefu’s Super Gold 2 description explains one process using atomised steel powder, compacting, sintering, forging and rolling. Mizutani uses Nano Powder Metal as its own material name on selected scissors. Kasho lists SG2 on a different named model. Do not treat those names as interchangeable.
| Model | Maker-published material and use | Buyer check |
|---|---|---|
| Mizutani SCHOREM MASTER Nano | Nano Powder Metal cutter in 6.0, 6.5 and 7.0 inches; listed for blunt cutting | Match blade length and handle to your cutting work. |
| Mizutani Z DUAL ZD-3 | Nano Powder Metal thinning model; Mizutani states a 15% cut rate | Check tooth configuration and removal rate for your texture work. |
| Kasho SlideCut KSL-65 OS | Kasho Europe’s 6.5-inch SG2 powder-steel model with a moving-blade mechanism | Assess the mechanism, fit and local service as well as material. |
Takefu describes a fine, uniform structure for its own SPG2 material, and Mizutani describes the effect of its material and heat treatment on its blades. Those statements do not establish a months-long sharpening schedule, a friction ranking or a universal hardness for every powder-steel shear. Kasho publishes a 61–62 HRC material figure for its SlideCut model; it should not be transferred to Mizutani’s models.
Mizutani’s product manual warns that its very fine new edge can chip if thick bundles are cut or the screw is loosened when first used. That is more useful than assuming all powder steels are drop-proof. Ask who will sharpen the exact model in your market, how its edge should be maintained, and whether the mechanism or finish changes service terms. Compare Mizutani and Kasho models by technique and fit first, then use the published material specification to narrow the choice.
