Originally, handpieces varied little in design as the common use was to push with the handle placed firmly in the center of the palm. With modern pneumatic engraving systems, handpieces are designed and created in a variety of shapes and power ranges. Handpieces are made using various methods and materials. Knobs may be handmade from wood, molded and engineered from plastic, or machine-made from brass, steel, or other metals.
