A utility knife, also known as a box cutter or a razor blade knife, is made up of (a) a simple flat holder, usually made of plastic or metal that measures three to four inches long and one inch wide, and (b) a standard razor or a specialized double-sided blade. Most utility knives have adjustable or retractable blades, making them ideal for any type of cutting. Once its blade becomes dull, it can be easily resharpened or replaced with another one. Utility knives are very handy in the kitchen and also outdoors, usually camping or hiking.
A straight-edge blade utility knife is ideal for cutting and slicing meat, fruits, and vegetables. The most popular straight-edge blades are taper ground, hollow ground, convex ground, flat ground, and chisel ground blades.
Serrated blade utility knife
A serrated blade utility knife features a blade with a combination of a sharp edge and a serrated edge. It can slice through breads and pie crusts without damaging them. It is easy to sharpen and require less maintenance than a straight-edged blade. However, serrated blade utility knives easily become dull after extended and frequent use.
A rounded serrated edge utility knife, also known as a scalloped or wavy knife, is less abrasive than the one with pointed teeth and does not work well in slicing the top crust of breads.
Durability: Choose a utility knife made of tough and high-quality metal. They may seem to be more expensive at first, but they usually last longer to give you more value for your money.
Compact: For camping applications and other outdoor activities, choose a compact and lightweight utility knife that is easy to carry.
