Abstract: A tool that seats and cuts multiple wires inserted into terminals of a multi-terminal jack includes a support housing for a linearly translatable, and removable carrier. The carrier fixedly retains one of a blade head and a jack, and slidably retains the other of the jack and the blade head, in such a manner that the jack is maintained in precision alignment with the blade head as the carrier is linearly translated within the support housing. A carrier translation control mechanism is coupled to the support housing in a manner that pushes and thereby linearly translates the carrier, so as to bring the blades of the translated blade head into precise stuffing and cutting engagement with the wires in the jack.
