A Smooth Metal Compass for Geometry, Drafting and Design This German-made quick-set geometry compass offers smooth, fine adjustment, sturdy metal construction, and steady precision for geometry lessons, drafting, technical drawing, and creative geometric design. Part of the Faber-Castell Factory Blackstone Stream Series, this compass has a matte black finish, precision gear-wheel adjustment, and a sturdy, balanced feel in the hand. The quick-set mechanism makes radius changes easy while helping students draw clean circles, arcs, and geometric constructions with consistent control. This is a refined everyday compass for students who want more precision than a first school compass, without the added extension bar or adapters used for advanced large-scale drafting. For beginning geometry work, see our First School Compass for Students. For larger circles, colored pencil use, and expanded drafting options, see our Adjustable Quick-Set Bow Compass.
