I have purchased a new one since the nippers that I used to date have gone out. It is natural that I just bought it, so I'm looking forward to what extent I can maintain sharpness. Besides sharpness I think that it is generally easy to use and a good product.
It is a micro Nipper of Fuji arrow which is well established. Copper wire thinner than hair is cut. If you change the indication of hardness it will be 59 ± 2 and it is 1 to 2 harder than those of other companies. Such a thing should be used exclusively for copper wire and the blade is painful when processing piano wire and ceramic parts etc. There is no problem for parts used for plastic nippers and nail clippers.
