The best designs are often the most simple, and this 'Whisk' by Ivan Zhang proves such a point. If you're doing a spot of baking and need to separate your egg yolks from the rest of the egg, all you have to do is pop them in the specially shaped groove at the top of the whisk.
With the square shaped handle of this whisk, you can even place it down on the counter and it won't roll off and make a mess. This slick design will save you a lot of time if you're a keen baker, and will even help you fluff up your cake mix too. With all this time you'll have saved preparing your delicious baked goods in the kitchen, you can spend more time enjoying them.
