Getting curved surfaces in trim, millwork, tiling, laminates, cabinets, and floor work to match right can be a real trick. This enhanced version of the original AccuScribe makes it easy to maintain a consistent scribe offset, staying parallel to the object surface every time. It has the added ability to be used as a compass or marking gauge, along with a handy built-in pencil sharpener. Comes with pencil and 2 scribe tips. USA
