  • Patent number: 10869715
    Abstract: Methods and devices are described for the design and manufacturing of a knife with a robust double bevel cutting edge profile for use in surgical procedures. The double bevel cutting edge profile may be defined by a combination of a cutting edge angle and a radius of the cutting edge tip. In some embodiments, the cutting edge profile may be defined by a combination of a web thickness profile and a radius of the cutting edge tip. Numerical ranges are identified for each of the various geometric parameters which may define a cutting edge that provides sufficient knife sharpness over many cutting repetitions. In some embodiments a medical device, which implements a knife with a cutting edge, for use in surgical procedures is described.
