My julienne peeler.I learned about this tool a few years ago and thought about it for a few months before buying it at Bed, Bath and Beyond. It's perfect for making match stick size carrot slices for soups, salads and stir fry.
See the "teeth"under the blade:
As you slide the peeler down the carrot, these "teeth" cut the thick slices again to create the long thick cuts. Then you cut the long strips with a knife to make them shorter if you like...Simple and easy to use.
