"Juliennes cutter fan"
Try the regular SharpPeel Juliennes, it works very well on carrots & courgettes. I do a little bit on one side, doing small sections at a time like 1/2 or 1/3 section ( slide off the Juliennes on each or every couple of turns) You now have a flat side so turn it over so it is flat on the surface and carry on doing sections, remembering to slide them off. When you can no longer do sections, you can try on the side of what is left but you will have to cut the small bit remaining with a knife (not a big deal at all)
