The pair of cutting blades are pin joined to each other at their terminal webs which are joined to bow handles. A ball bearing is mounted to the pivot pin by way of an antifriction spacer for providing a permanent spacing between the terminal webs in order to prevent the same from abrasion and consequent uneven wear. A clamp is coupled at one end to the pivot pin projecting from one of the terminal webs, and anchored at another end to the other terminal web, in order to bear the component of cutting resistance which tends to spread the pair of blades in opposite directions away from their parallel planes of motion.
