Pencils are used to write and mark out clearly visible lines on nearly all surfaces irrespective of material or grain.
They are used to mark materials with lines and shapes that are then followed as accurate guides for the cutting and shaping of the materials.
Carpenter’s pencils are also used by builders and bricklayers, and in many other trades, as they are designed for use on heavy-duty materials such as timber, stone and concrete.
Note: these pencils may not work well on some metal, polished or glazed surfaces.
