Four Fold Rule

Also sometimes referred to as blindman's rules because their bold markings enabled the rule to be used in the dim light of a workshop with windows covered in sawdust and encrusted with cobwebs. Both rules are 18mm wide, four-fold and fitted with brass hinges and, in the case of the wooden version, protective tips as well. The wooden version is calibrated zero to one metre in millimetres on one side and zero to 36" in eighths on the other. The plastic version is similar but has one sixteenth divisions on the imperial side. A pair of very handy rules; tools much loved by the traditionalists amongst us.
