The pliers are made of chrome vanadium steel, which performs better than the carbon steels commonly used on the market. Durability and hardness are increased by 30-50% and shear life over 20,000 times. EFFORTLESS DESIGN: for the material of the pliers handle, we use TPE material which is twice as expensive as ordinary rubber. This makes the powerful pliers more elastic and more comfortable, and they perform better than rubber handles in terms of oil resistance. Allows you to freely use powerful pliers in oily environments. ECCENTRIC ANGLE DESIGN: Patented eccentric angle design efficient, it saves about 30% effort compared to ordinary pliers. Allows you to easily carry out long-term cutting work. Versatility: Mechanical maintenance, domestic engineering. ELECTRICAL INSTALLATION (Warning: To ensure safety, please try to use it when the power is off; when the insulated handle of the electrical installation is damaged, do not cut the live wire.< /li> Size: 12 inches
