I think it has to do with the variety of juniper and it must be in winter in Japan.

Rene Voortwist common only in bonsai nursery with small wire.

Apparently, in Kimura Nursery, the pruning scissors he and his apprentices use is made of special steel which is cheap but also very strong to cut metal without getting blunt in a short amount of time. In Japan, they do not manufacture this bonsai steel anymore, Kimura and his apprentice use to cut small wire and branches because it is more efficient and they know the scissors can handle it. I learned this from Ryan Neil.

@@MrYoumitube I did not know that. Thank you for explaining! 👍
