Box Joint vs. Lap Joint
Lap joint: The two plier halves lie on top of each other but are not milled out.
Box joint: One handle on the pliers is slit. The other handle is pushed through this slot. This joint connection can withstand a high level of load and strain because the joint bolt is supported on both sides and the inside handle is double.
Tungsten Carbide Inserts (TC)
Tungsten carbide (chemical formula: WC) is a chemical compound (specifically a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes for use in industrial machinery, cutting tools, abrasives, other tools and instruments.
Tungsten carbide is approximately two times stiffer than steel, with a Young’s modulus of approximately 550 GPa, and is much denser than steel or titanium. It is comparable with corundum (α-Al2O3), sapphire and ruby in hardness and can only be polished and finished with abrasives of superior hardness such as cubic boron nitride and diamond.
