The ENGINEER PZ-57 neji-saurus screw removal pliers will remove problematic ruined small / mini-sized screws quickly with ease. Crafted in Japan, the plier's unique jaw groove and lip design, allows you to firmly grip a screw and simply twist it out (normal pliers would just slip off) - the jaws can even grip & extract truss head screws (low-profile dome heads) as well custom/specialized and tamper-proof screws.
