ABSTRACT:
A compass having a pivot portion with an open faced clamp and a utensil portion with an open faced clamp, so that the portions can be clamped onto intermediate bars of varying shapes and sizes. The utensil holder is also angularly adjustable with respect to the pivot point so small circles can be drawn. Only the pivot portion and the utensil portion need to be transported because suitable intermediate bars would probably be available at the location where work is to be performed.
