A few years back, I purchased some Cutco knives, which I dearly love. The handles are ergonomic and made from a very hard plastic so they can go in the dishwasher for better cleaning; the blades are very sharp and rarely need to be sharpened. They also have some other things that work quite well. Last week, while making chopped salad, I saw the pizza cutter which looks like the rotary cutter used in quilting. It was an a-ha moment. This is what I did with it. Finely chopped cucumber in a matter of seconds. It worked on green onions also. Not so well on tomatoes. I am now on the lookout for other candidates. It's nice to try new things.
