Wave Edge and Jigsaw Rules These wave edge rules, except large and extra large, have a flat body, waved on the edge only. All rules are supplied tip hardened to give a long cutting life, similar to that of an extra hard cutting rule. These jigsaw rules can be supplied in any pitch from 19mm upwards. Usually made from 2 point Flexicut with a long bevel/centre bevel cutting edge, tip hardened.
