IMO these novel scissors don't really represent the achievements of Japanese scissor-making. The market for high-quality hairdressing and barbering scissors and tailoring shears is now almost completely dominated by Japanese manufacturers.
There are two makers left in Sheffield (William Whitely and Ernest Wright), a handful remain in Solingen, but Japan has dozens of high-end scissor manufacturers. It's a remarkable niche success story, built on a careful combination of design innovation and traditional craftsmanship.
