The Ulu Knife has been used by the Alaskan Eskimoes for centuries. It is now very popular for chopping herbs, garlic, egg salad, salsa, tuna salad, etc. etc. etc. The bowl is the same shape as the stainless steel blade of the ulu knife. Therefore you do not have to rock the chopper back and forth, just go up and down and you will be amazed how wonderful it is. I personally use it to cut pizza that is delivered with all the cuts covered in melted cheese. Turn the bowl over and you have a cutting board.
