Another fun summer tool is this cherry (and olive) pitter at Williams Sonoma. We eat a lot of cherries in the summer, but the seed is really annoying. So, this makes it really easy to pop the seed out and serve cherries- which are so healthy and yummy! (Here is an article about the health benefits of a Cherry http://www.whole-food-supplements-guide.com/nutritional-benefits-of-cherries.html)
One more fun tool that I use a lot is a biscuit cutter, and I have never made a biscuit! We use biscuit cutters to cut sandwiches into circles (apparently they taste better to the girls in a circle), we cut rice crispy treats with these, brownies, you name it! It is a lot easier to use than a cookie cutter because they are so thick and sturdy. I guess you could make a biscuit too if you want!
