The main purpose of the marker is to serve builders during the construction process. It is designed to mark on different types of surfaces and reach narrow spaces and deep crevices. The rounded rectangle shape provides a solid grip and precision control, while the hexagonal shape prevents rolling. The detailing visually references a wooden pencil which serves as a design differentiator. One of the most common problems with craftsman’s pens is that they are always misplaced. We noticed that having holsters instead of clips led to the pen being put back more often. The holster has a built in sharpener.
