Jiya Zero Pliers 175mm - Micro-mirror blade finish - Eccentric lever design - Weight: Approximately 340 grams - Chrome vanadium steel - Cutting capacity: Iron wire Φ3.4mm / Copper wire Φ4.0mm / VA VVF wire & eco-wire 2.6mm x 3 cores -- From the instruction manual -- The "Zero Series" is a series that boasts the highest quality among our product lineup, excelling in sharpness, durability, and design. It is a first-class product, the culmination of over eighty years of our company's history. The materials for this product are forged from special chrome vanadium steel, commissioned from Kobe Steel, Ltd., achieving high levels of durability, wear resistance, and toughness. The remarkable sharpness of this product is achieved by employing a "micro-mirror blade," where the blade is polished to a mirror-like finish using cutting-edge polishing technology, and then meticulously finished one by one by skilled blade craftsmen. This minimizes friction during cutting, resulting in an astonishing sharpness. In addition, an eccentric mechanism based on the principle of leverage is adopted in the head of the main body. This allows for lighter cutting compared to our conventional products. Furthermore, the grip is designed based on ergonomics to provide a shape that reduces fatigue even during long hours of work. The material used is an elastomer that is soft and fits comfortably in the hand. It is also an environmentally friendly product as it does not emit toxic gases during combustion. I purchased this new, but it has been stored without use. The box has some damage, but the pliers are new and unused.
