The Shun Kanso Utility is between a chef's knife and a paring knife in size, but with a narrower, straighter blade. It's perfect for tasks where precise cuts are needed, such as trimming green beans or other small vegetables. Its slightly curved belly enables it to do moderate rocking cuts, too. Utility knives are sometimes called sandwich knives because they work well on almost everything that goes into a sandwich—from thin-skinned vegetables, such as tomatoes, to meats and cheeses.
