The pliers also feature a high-leverage design with the rivet placed near the cutting edge, increasing cutting force by about 36%, making tough jobs easier. The hot-riveted joint helps ensure smooth action without any handle wobble, adding to the tool's sturdiness. Being made in the USA by Klein Tools, a trusted brand, adds confidence in quality. On the downside, the set weighs 2.6 pounds, which might feel a bit heavy for prolonged use if you prefer a lighter tool. Also, the handle material is plastic rather than rubber, which some users might find less cushioned.
