Make a game of Operation more fun with this Table Saw. Okay, maybe this is better left to food prep. Made from high density food grade plastic with sharp, serrated teeth, this large-scale, saw-shaped knife has a big, easy-to-grip handle, and can both cut and serve your birthday cake. It's durable enough to cut through veggies and crusty bread. Bonus points if you cut open a pomegranate or strawberry cake or some other bleeding food.
