Rule/One

This drafting tool by HMM couples the two things necessary to draw a straight line: a pen and a ruler. The Rule/One seamlessly fits these two things together. The 13 cm ruler acts as the cap of the pen. The two combine into one hybrid object and separate to function as a pen and ruler. The Rule/One comes with hardware to hang this pen from a keyring or strap. Available in black with gold lettering and black with silver lettering.
