Prepare no joy ...

Of course you would expect with a relatively large diameter for all 3 to nothing - but unfortunately that's what you get ... is preparing for cutting no pleasure, but because you have to press quite a lot - it's just not sharp enough.
I then tried it himself regrind tidy - even that was not really successful since then is probably just the material too cheap. We will use now when it comes, for example, time to shred chocolate or other things for which you need a knife that is not to be sharp and may even break down ... In this respect, 3 stars (not bad) - but also no more.
