Any kind of knife used for routine manual labor is referred to as a utility knife. Originally, these were fixed-blade knives with sturdy cutting edges that could be used for tough jobs like bending wood, cleaning fish scales, butchering animals, cutting cordage, and cutting or scraping hides.
A utility knife, sometimes known as a petty knife, is a smaller, more adaptable tool for jobs demanding control and accuracy, filling the gap between a chef knife and a paring knife. A chef knife is a larger, more versatile tool for general chopping, slicing, and dicing.
A "utility knife" or "petty knife" is a multipurpose, mid-length kitchen tool that falls between paring and chef's knives in size. It can be used for a variety of activities, such as chopping, slicing, and dicing smaller foods.
The blades of construction utility knives, which are usually composed of sturdy molded plastic or die-cast metal, may be replaced and retracted, and the operator can change how far the blade protrudes from the grip.
