Core functional modules High quality material, corrosion-resistant and wear-resistant Material selection: Made of T316 stainless steel, with a galvanized surface for strong protection. Core features: It has excellent rust and corrosion resistance, as well as wear resistance, durability, and long service life. 7 × 7 structure, stable and non collapsing Structural design: The structure adopts 7 sets of steel wires (7 per set) spiral wound with stranded cores, tightly wound. Core advantages: Higher strength, less likely to sag or deform during use, and neat and even cutting after cutting. High tensile strength, durable and long-lasting Fracture strength: up to 1700 pounds (approximately 771kg), excellent tensile performance. Usage value: able to withstand high tension, not easy to break, and extend the service life. Comfortable to use, with a gentle touch Surface treatment: Using polishing technology, the surface is smooth and free of burrs. Experience advantage: Gentle contact without cutting hands, safer and more comfortable operation.
