This cutter is actually a super part. I cut so mushrooms, potatoes, etc. Unfortunately there is a design flaw which, although done after some time the use of itself, however, a non-negligible harmful to health effect (therefore only 3X, otherwise 5X): The two pliers parts are indeed out in the area of the cutting head to each other, so it really should not be a collision of the knife to the cutting grid on the other side (so it the developer has determined pictured), but comes with additional lateral bending of the knife when cutting harder cutting material but it blocked the collision and the device! This disturbing stop can be overcome through increased effort but what then, however, leads to cutting small plastic splinters from cutting grid, which then end up in unnoticed cut sliced and then also in the stomach of the connoisseur. Until I found out that some mm² plastic have already been scraped off (and are now either in the water treatment plant, or even in my belly) My recommendation: Use a nail file, the vulnerable edges on cutting grid wegarbeiten, before using this otherwise well-usable device for the real thing.
