Abstract
A hair clipper bladeset includes a stationary blade having a front, stationary toothed edge and an opposite, stationary rear edge, the stationary blade defining a transverse track, a moving blade having a front, moving toothed edge and an opposite, moving rear edge, and a lower blade guide disposed between the moving blade and the stationary blade and configured for reciprocating in the track and maintaining lateral alignment of the moving blade relative to the stationary blade during lateral reciprocating movement of the moving blade. The moving blade has an engagement formation. An upper blade guide connects with the engagement formation for moving with the moving blade in the lateral reciprocating movement. A drive arm has a blade end operatively engaging the upper blade guide, and an opposite follower end configured for receiving a hair clipper drive element, the drive arm pivots about a drive post located on the stationary blade.
