Abstract: 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.
