Abstract
The invention relates to a pair of scissors and a mould and a method for the manufacture of a pair of scissors. The scissors comprise two scissor blades of metal, a ceramic material or the like, and two plastic handle portions which both form a tongue positioned on the outer surface of the blade and surrounding the scissor hinge. By virtue of variation in the position of the hole of the blade, through which hole the scissor hinge goes, the points of the blades and the counter faces of the handle portions must be finished manually. This can be avoided if at least one hole has a larger diameter than the outer diameter of the hinge pin so that the bearing surfaces formed by the tongues can, if necessary, be placed eccentrically with respect to the hole of the blades.
