It is difficult to get out of hand. When cutting and cutting in condition, as soon as the blade got bowed, it broke with Pokin. I wish it had a little more stickiness, but 3 replacement blades quickly disappeared. I think that it can be said to the tools in general, if it thinks to use about 1 or 2 times, if it is used frequently, you should buy something like that. The sharpness itself is like an ordinary gold saw.
