A wire termination and cutting tool, RJ jack and RJ jack and tool termination system is provided with the tool having a cutting module support portion and an RJ jack support portion connected to the cutting module support portion for relative movement with respect to a pivot point. An RJ jack is connected to the RJ jack support portion. The RJ jack includes wire termination locations each with an insulation displacement contact (IDC) with a cutting/clamping slot. A cutting module is connected to the cutting module support portion. The cutting module includes cutting blades for cutting wires and wire insertion parts. An actuator applies force for in curved relative movement of the cutting module support portion with respect to the RJ jack support portion. The cutting module support portion is aligned with the RJ jack at an end of the curved relative movement whereby the wire insertion parts are aligned with slots of corresponding insulation displacement contacts of the RJ jack.
