发明名称 Craft ruler with laser guide
摘要 A craft ruler employs a laser module which is longitudinally positionable along the ruler. A laser emits a beam which defines a crafting guideline on an adjacent surface. The angular position of the laser guideline may also be adjusted relative to the straight edge on the ruler. In addition, more than one ruler may be ganged together to form orthogonal lines or a grid.
