So for us the peeler has been about half a year in use and there are all the fingers off. Of course, the blade is sharp and she is supposed to be. I do find it rather a feat to cut here, if you have understood the operation of the thing once (you hold the cutter firmly, turning or tipping the Radi - not vice versa!). Maybe men's hands are compared to fairy-hands here a little advantage because you pack a little harder and make stops at fixed "acute" need. Like the Spitzer also, sharpener and pencil extent have reasonably good match. Therefore rather thick Radi with about 6-7 cm diameter bring the best results - in my opinion. With practice, the then beautiful Radi-accordions. Another advantage is a real space-saving part!
