Allinone electrical tool for cutting, stripping, twisting, and testing wires Allinone function: combines cutting, stripping, wires twisting, and voltages testing in a single tool to speed up installations and reduce tool switching. Live wire detection: hearable (audible) and visual alarms warn of live conductors, helping prevent shocks and guiding safe work. Durable and precise: wearresistant alloy steel cutter delivers clean, accurate stripping; supports, crimping, and wires pulling with reliable performance. Ergonomic and comfortable: ergonomic nonslip handle designed to reduce hand fatigue during extended use. Safe storage: integrated secure feature locks the cutter when stored to prevent accidents. Onsite troubleshooting ready: builtin voltages tester and a delicate, portable design suitable for junction boxes, control panels, or outdoor installations. Quick feedback: double LED and hearable alerts provide fast voltages feedback to confirm circuit status. Versatile upgrade: a multifunction tool that fits professional toolkits and home workshops alike. Use scenarios 1) In a junction box while installing or repairing lighting, use the tool to cut, strip, twist wires, and verify voltage status before final connections. 2) Servicing a control panel in a tight space: strip and twist wires while checking for live circuits to avoid accidental contact. 3) Outdoor electrical work such as installing or servicing outlets or equipment: safely prepare conductors and confirm circuit status on site with the builtin tester.
