Found this fabulous chopper at BBB in their enormous kitchen section (another thing I like). I like it so much because it allows you to chop an onion without any tears.. You just twist the top, and the gears inside spin the double blades, when your done just shake it out, or you can take out the blade and put the whole thing in the fridge.. I was going to try the Slap Chop, but since Vince Shlomis recent charge, I've decided to wait for another brand.
