1. A drive assembly comprising:
a working end; and
a drive beam assembly including a core member and outer laminates, the core member including a flexible beam having planar side walls, the flexible beam having a distal portion secured to the working end, the outer laminates supported along the planar side walls of the flexible beam such that longitudinal movement of the core member causes longitudinal movement of the outer laminates, wherein the core member is formed from a metal and the outer laminates are formed from a material having a lower coefficient of friction than the core member.
