A rollable ribbon separator tool for separating fibers in a rollable ribbon, the rollable ribbon separator including a chassis having a length and a guide surface along the chassis length for receiving a first portion of a rollable ribbon in a flattened position, the guide surface for positioning the first portion of the rollable ribbon having a first node with selected fibers to be separated, the selected fibers being positioned flat on the guide surface. The rollable ribbon separator includes a blade securable to the chassis, the blade having a cutting edge positioned toward the guide surface at an acute angle to the guide surface. The angle of the blade cutting edge with respect to the guide surface allows the cutting edge to urge the first portion of the flattened ribbon fibers against the guide surface when the fibers are drawn through the chassis along the guide surface.

A tool for removing insulation in mid-span of a cable carrying a signal-transmitting conduit comprising a lower body section and an upper body section movable toward and away from the lower body section. The tool includes a curved mandrel disposed on the lower body section, the curved mandrel having a central peak portion and adjacent portions curving downward away from the peak portion, to present a mid-span portion of the cable insulation on a side away from the mandrel peak portion. The tool includes a blade disposed on the upper body section, the blade movable toward and away from the curved mandrel. The cable is securable in the curved mandrel in a curved position, allowing the blade to shave the cable insulation allowing access to the signal-transmitting conduit. The tool may include an adjustment barrel having a plurality of height adjustment surfaces disposed at a different distance from the barrel axis, each height adjustment surface positioning the blade a different distance from the mandrel.

A cable stripper having a displaceable blade carriage, which is normally biased toward a cable support to automatically accommodate differently dimensioned jacketed cables in a desired position. The blade carriage supports a blade assembly configured so that the blade can be displaced among multiple positions, corresponding to respective axial, radial and a plurality of spiral cuts, while the cable is engaged in the desired position.

An adjustable wire stripper has a jaw for positioning a length of cable, a tool body for tangentially contacting the cable, a blade having a cantilevered loading ramp for cutting the insulation off the cable, and a blade angle adjustment shaft driven by an angle adjustment member. A frame member disposed between the jaw and the body adjusts the distance between the jaw and the body to accommodate cables of different diameters. The frame member relatively moves the jaw and the body with respect to each other along a line having a constant sliding angle. The angle adjustment shaft has a flange extending radially outwardly for driving the shaft to different angles of rotation with respect to the body. An optional assist spring bearing opposite the flange urges the flange against the blade angle adjustment member during movement of the flange to reduce backlash of the shaft.

A handheld circular sawing device for severing armored cable includes a housing. A first plate is coupled to and extends coplanarly with a first side of the housing. A second plate is positioned substantially perpendicular to the first plate along a lower edge of the first plate. The second plate is hingedly coupled by a first end to the first plate proximate to a rear of the housing. A second end of the second plate is positioned proximate to a front of the housing to define a channel. A power module and a motor are coupled to the housing. The motor is operationally coupled to the power module. A blade that is coupled to a shaft of the motor protrudes into the channel. The motor is positioned to rotate the blade coincident with the shaft to longitudinally cut a section of a tubular substrate that is positioned in the channel.

A pair of tool parts which include a first and a second tool part, can be secured exchangeably in tool jaws of a hand-held tool and can be moved together by means of the tool jaws, for enclosing a cable, encapsulated with an insulating sheath, over a part of a length of the cable. A receiving region of the tool parts formed when moved together, encloses a semi-circular region of the cable in cross section with a longitudinal dimension and a transverse dimension remains for the cable in each tool part. The receiving region is penetrated by a blade and has an inwardly pointing clearance. A plurality of blades are configured in each tool part, and the blade tips run in accordance with a helical line when the tool parts are moved together. Methods for stripping a cable are also provided.

An insulation stripping tool can be used to precisely remove a section of insulation located away from the edges of an insulated wire. The insulation stripping tool includes two transverse cutting elements which can be spaced a predefined and precise distance apart, and upper and lower longitudinally-extending cutting elements extending between the transverse cutting elements. Hinged lever arms can be gripped to move the cutting elements towards one another and cut into the insulation sheathing an insulated wire. A depth guide may be included to control the depth of the insulation cut to minimize or avoid scoring or otherwise affecting the conductive core of the insulated wire.
