I've seen this Grater with my girlfriend and had to necessarily have. They warned me that they very !! is sharp. But a savvy cook has indeed no problem .... na? On the first try the forefinger mitgehobelt-ouch.
Only negative there is no protection of the friction surface in order to safely store the charge. (One star deduction)
Conclusion: The grater works great! But beware .... looooong sharp !!
