Staedtler Halfpipe Pen-style Compass

At first glance, this uniquely designed tool appears to be a stylish pen or pencil, complete with a shirt pocket clip, but upon closer inspection and after a minor adjustment, it quickly becomes apparent that this implement is a precision measuring and technical drawing compass. To provide extremely accurate settings, it features a patented equal-spread mechanism. It's sturdy metal barrel and solid pivot point make damaging it very difficult, while it's soft rubberized grip and handle make using it very comfortable. For increased durability and for the sake of safety, a matching cap protects both the lead pointer and the needle. Further contributing to this excellent tool's mystique, it has a hidden but easy access lead storage compartment. Maximum Circle Diameter Created: 12 in.
