Japanese scissor seller with appointment-based trials; SG2 is documented on named models and lines.

Alpha Scissor Co.’s company page gives a January 2006 establishment date and a Kichijoji, Tokyo office. It also lists several locations where customers can try physical scissors by appointment. That trial route is useful if you are deciding between handles or lengths; confirm that your exact model is available before travelling.
The high-grade catalogue lists SG and PR cutters in powder steel SG2. The basic cutter catalogue also identifies SG2 on named BM and BC models. The thinning catalogue lists SG2 for the SGT line, while also showing other thinning families. These pages support those model and line statements; they do not turn SG2 into a specification for every alpha scissor.
A cutter and thinner answer different questions. Start with the motion and length you use most, then compare the actual handle and blade line. For thinning, read the individual tooth count and maker cut-rate statement for the exact code rather than assuming all thinners with the same material remove the same amount of hair.
Request the current model code, hand, price, shipping destination and service terms from the seller. The maker’s yen prices and Japanese office appointments cannot be carried over to another region. See the powder-metallurgy guide for why an alloy name is only one part of a finished shear.
The company page lists a Kichijoji, Tokyo office and says Alpha Scissor Co. was established in January 2006.
No range-wide grade is established. The maker explicitly names SG2 on the SG/PR high-grade cutters, selected basic models and SGT thinners.
The company page lists appointment-based trial locations in Japan. Confirm the current office, available model and appointment before travelling.
