I bought it for the purpose of making a circular cut at 360 °. It is very good to shred without having to change hands with sharpness or ratchet structure, but because the blade rotates, it is attached to the backlash, the start and end of cutting do not connect beautifully, and the place with some difficulty in appearance is dissatisfactory .
I like the ratchet mechanism. Because it is a rotary blade, I am satisfied with pushing without pulling the object. Due to its high frequency of use, the shaft of the rotary blade (made of brass) wears out intensely and wears out. If the cutter is a consumable item, at least the shaft must last longer. Ama-chan is to use a material that is softer than consumables?
