Not only does a dull blade make slicing and dicing more difficult, it can actually make working with knives a little dangerous. An unsharpened blade is more prone to slipping off food than cutting it, and then ending up somewhere painfully unwanted. So Joseph Joseph has created a cutting board with a built-in knife sharpener so you can be sure your blades are sharp before you get to work.

For just $20 the cutting board's built-in ceramic sharpener means there's one less kitchen gadget you have to cram in a drawer, and of course it's also good for chopping, with a rubber edge that stops it from sliding all over your counter while you work. [Joseph Joseph]
