Pliers have excellent shape but the material is quite prone to bending, metal fatigue and eventual breakage. The pliers probably need strengthening on the legs and bends near the rivets as that's where most of them broke. The quality of the steel is also worth considering. This is probably the most ergonomic drill removal tool I have ever seen. Doesn't handle offensive handlers very well. Most of the several hundred tongs died horribly after only six months.
