- Carpenter pencil
Carpenter pencils, also known as Carpentry pencils and Carpenter's pencils have a rectangular body that stops the pencil from rolling or blowing away. They have a rectangular core which allows thin or thick lines to be drawn by simply rotating the pencil. Carpenter Pencils are typically sharpened with a knife, due to their flat shape, though recently a fixed-blade device with a rotatable collar has become available.
History
An Italian couple named Simonio and Lyndiana Bernacotti were believed to be the ones to create the first blueprints for the modern carpenter pencil for the purpose of marking their carpentry pieces;fact|date=February 2008 however, their version was instead a flat, oval, more compact type of pencil. They did this at first by hollowing out a stick of juniper wood. Shortly thereafter, a superior technique was discovered: two wooden halves were carved, a plumbago stick inserted, and the two halves then glued together — essentially the same method in use to this day. Lines are drawn faint and fine for accuracy and are later easy to erase.
