<p>A surgical knife blade for forming an incision in bodily tissue comprising a body having a cutting edge terminating at a distal tip, said cutting edge including opposing cutting edge segments extending distally to meet at said tip, said cutting edge being configured by blending a first and second radii,. The first radius is concave and the second radius is convex, the first and second radii meet at a juncture which forms a smooth tangential connection, whereby the blended radii form a hollow design and wherein when said body is moved in a cutting direction transverse to the tissue to cause said tip to enter the tissue, less force is required to penetrate the bodily tissue and greater control is provided.</p> |
