Disclosed herein are tools, systems, methods and surgical techniques for a disposable grasping, cutting, severing and/or biting surgical instrument having sharp cutting tips. Such instruments are lighter than their equivalent stainless steel instruments currently being used, and can be designed to employ a shearing/cutting or grasping mechanism that may be suited for specific cutting and sampling bone, cartilage and soft tissue. The surgical instrument includes a slideable upper body that may have an overmolded or removably connected cutting tip assembled onto an advancing face that translates along the handle body to produce a shearing, cutting or grasping action of tissue positioned within the jaws.
