The tips are either straight or curved to enable surgeons to reach tissues with difficult access. Jaws of splinter forceps have either a smooth inner surface or are lined with transverse serrations for a firmer grip. Some types of Surtex Instruments splinter forceps, such as Feilchenfeld, Hunter, and Shaaf splinter forceps, have an additional expertly-crafted longitudinal groove along the transverse serrations on the inner surface of their jaws to optimize object grasping. Stieglitz, Peet, and Ralk forceps are other types of splinter forceps manufactured by Surtex Instruments. Splinter forceps are commonly used in general surgery.
