A surgical knife blade for forming an incision in bodily tissue comprising abody having acutting edge terminating at a distal tip, said cutting edge including opposingcutting edgesegments extending distally to meet at said tip, said cutting edge beingconfigured by blending afirst and second radii,. The first radius is concave and the second radius isconvex, the first andsecond radii meet at a juncture which forms a smooth tangential connection,whereby theblended radii form a hollow design and wherein when said body is moved in acutting directiontransverse to the tissue to cause said tip to enter the tissue, less force isrequired to penetrate thebodily tissue and greater control is provided.
