Precise stripping holes for a clean cut - The stripping holes are precisely designed to deliver clean insulation removal while reducing the risk of conductor damage. This helps improve reliability and protects wires during maintenance and installation. Durable and attractive finish - The tool surface is black after fine polishing and treated with rust protection oil, offering a durable, corrosion resistant finish that remains attractive through regular use. Wide cable compatibility - Compatible with multi-core cables such as RV, RW, BVR and BWB, making it suitable for common electrical and electronic wiring tasks. Not suitable for high hardness wires such as BV single core. Strong, durable construction - Forged from 65# manganese alloy steel with full heat treatment for high hardness, a sharp edge, and long-lasting toughness. Built to withstand repeated use without deforming. Usage scenarios - Electrical installations and repairs in homes or offices: strip insulation from RV/RW/BVR/BWB cables efficiently at outlets, panels, or junction boxes. - Workshop cable preparation for electronics, appliances, or small projects: quickly prep multi-core cables with clean cuts to ensure reliable connections. - On-site maintenance and field wiring: perform clean, damage-free stripping in construction sites or service calls where reliability is essential.
