Can I please get a volunteer from the audience? The Sharp Act Knife Sharpener is the perfect magic trick. Not only does your volunteer remain unharmed, but your knife comes out sharper and polished. Although a magician never reveals their trick, this knife sharper is made of a ceramic stone and is 8 inches wide and 2.5 inches tall. Enjoy your moment in the limelight, Foodbeasts. ($15 @ Mortimer Snodgrass)
