I have tried some peeler, because I suffer from an allergy to raw potatoes and a very sharp peeler need the least possible "injected". Buyer of this quite expensive peeler I was still skeptical, but already the first potatoes peeled almost by itself.
I was amazed at how may be a sharp peeler.
However, asparagus, carrots, peppers ... the WMF Peeler slides Duch everything as if through butter. I have it now. Almost 2 years use and despite regular cleaning dishwasher does not diminish its sharpness
Right now the asparagus season, the perfect asparagus peeler. The peeler cuts exactly the woody shell, no pulling threads remain. He is very efficient and does not peel off too much.
My absolute recommendation!
