A leather pyrography tool is an electric, pen-shaped device used to burn marks into leather. It usually consists of a handle, with a metal piece that sticks out with a connection point for a burning tip. The tips are interchangeable.
When the pyrography tool is plugged in, the tip heats up. Once hot, it can be used to burn different lines, shapes, patterns, and designs into leather. With a variety of tips available, it makes it very easy to burn patterns, shapes, and even calligraphy into leather.
