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 more than 20,000 times. EFFORTLESS DESIGN: For the pliers handle material, we use a TPE material that is twice as expensive as regular 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: Effective patented eccentric angle design, it saves about 30% effort per compared to ordinary pliers. Allows you to easily carry out long-term cutting jobs. 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.
