ABSTRACT:
A surgical knife is provided with angular cut control comprising rollers which extend along each side of the knife edge to maintain the knife blade in perpendicular relationship with respect to the surface being cut. The rollers additionally perform the function of smoothing out the surface to be cut and provide directional stability during the formation of the surgical incision.
