Abstract: Disclosed is a punch-down tool blade suited for seating, and seating and cutting data transmission and telephony wires into crowded patch panels. Also disclosed are embodiments of an elongated punch-down tool blade having a slidable locking collar which may be used in reversibly locking a punch-down tool blade with either the seating tip being used as the working tip or the seating and cutting tip used as the working tip without compromising both the ability of the tool tip to gain access to terminating clips or the tradesman's visibility of terminating clips so that patch panels may be efficiently and accurately wired while providing enhanced safety and decreased worker fatigue.
