| Compasses
|
Used for drawing arcs and circles, these range from simple Pencil Compasses to the more precise instrument used in Technical Drawing. As drawing instruments they can have Knuckle Joints to ensure the pencil lead maintains an Acute Angle to the drawing surface. The leg hinge may be a Firm Joint with the compasses set and held in position by Friction or Springbow compasses have a spring clip holding the hinge together and use a fine screw for adjustment.
