CASTROVIEJO Needle Holder, 5 1/2", curved, with lock and serrated jaws. Tungsten carbide inserts insure firm holding of needles and sutures. Carbide jaw needle holders. INTERESTING INFO: The notable and rare combination of physical properties possessed by tungsten carbide makes it useful for a variety of applications. It is extremely strong and wear-resistant. There are only a few materials on earth that can be used to cut or engrave tungsten carbide, with industrial diamond abrasives being one of these. Its tensile strength is very high, but it is brittle under high pressures as a result. The melting point of tungsten carbide is also very high, at 5,200 degrees Fahrenheit (2,870 degrees C). To boil, it must be heated much further, to an astronomical 10,382 degrees Fahrenheit (6000 degrees C). Our surgical instruments are constructed of very high grade stainless steel and the manufacturer is approved by the FDA.
