Sharpness is good, it is good for long-term use I would appreciate it if the blade length is a little longer

Convenient because the cutting edge does not slip without using a punch. Also sharpness is outstanding and other things can no longer be used.

Quality does not have any problem at all but I am using it all the time but it is stickier than the products of other companies and it is more thankful if the amount of money that goes well is a bit cheaper ...

Since we have been using it all the time, the quality is good. And most of all, the price is attractive. It is bad for past suppliers, but if thousands of yen is cheaper, I will buy it with Monotaro san. I wish I knew it sooner.
