I own and love a GSD Gemüsehobel decades. I just misled again by the advertising to buy a so-called V-planing. All were a disappointment! I have now bought myself a second GSD vegetable slicer - just in case! He has to keep a lot sharper than any competitor and easily cleaned. Sure, if you're not very careful, he will discolour when carrots, beetroot and the like. But that does not do the slightest interruption of function. There is nothing better!
