Engraving tools are used to create intricate designs and patterns on a variety of materials. The most common engraving tools are styli, stylets, and lasers. Styli are small, pointed tools that are used to manually etch designs into materials such as wood, metal, and stone. Stylets are similar to styli, but they are slightly larger and have a flat end. Lasers are high-powered beams of light that can be used to etch designs into materials with greater precision and accuracy than styli or stylets.
