Minimally invasive endoscopic cutting instruments having improved efficiency, access and reduced manufacturing costs are described herein. In particular, the present invention describes means for eliminating or modifying the distal end axial bearing surfaces so as to reduce manufacturing costs as well as the opportunity for galling and metal shedding. The present invention further describes an improved hub attachment method that may further or alternatively reduce overall manufacturing costs. The present invention yet further describes means and methods for improved bendability in the field, which, in turn, enables improved access to remote surgical targets.
