What kitchen implement is wedge shaped and has a sharp edge, perfectly suited to cutting a pizza without disturbing the topping, and then serving the slice?
That's right. A chef's knife. Sure, you could waste $10 on this pair of pizza scissors, which will do the same thing. But that's all they will do. I don't know which is worse. The fact that manufacturers continue to market uni-tasking tat, or that gullible consumers continue to stuff their kitchen drawers with it. What next? An egg cracker?
