a pair of blade cartridge assemblies, each blade cartridge assembly of the blade cartridge assemblies being adapted to engage with one of the one or more blade cartridge assembly tracks, each blade cartridge assembly further comprising:
a slider button assembly comprising a base plate adapted to engage with a slider button having a slider post adapted to travel through at least one of the slots of the blade cartridge assembly tracks, the base plate having a shaped opening and a shaped member with two engagement ends, each engagement end configured to be selectively received by the notches of the blade cartridge track to selectively lock the slider button assembly in a user-selected position relative to the blade cartridge track; and
a blade holder adapted to receive a blade.
5 . The cutting device of claim 4 , wherein the pair of blade cartridge assemblies are configured in a parallel position and to be deployable simultaneously.
6 . The cutting device of claim 4 , wherein at least a portion of the slider post and at least a portion of the shaped member are configured to be received within the shaped opening of the base plate.
7 . The cutting device of claim 4 , wherein a first blade cartridge assembly of the pair blade cartridge assemblies is aligned on a first side of the intermediate member and a second blade cartridge assembly of the pair blade cartridge assemblies is aligned on a second side of the intermediate member.
8 . The cutting device of claim 7 , wherein detaching the end cap enables each of the blade cartridge assemblies to be removed from between the housing shells and the intermediate member.
9 . The cutting device of claim 8 , wherein a top edge of the intermediate member is includes a notch adapted to receive a locking switch of the end cap to lock the end cap in a secured position on the rear of the intermediate member.
10 . The cutting device of claim 7 , wherein each blade cartridge is positioned on a side of the intermediate member, and the intermediate member comprises a pair of grooves on each such side, upon which each blade cartridge is able to move to stably extend or retract either of the blades from the housing.
11 . The cutting device of claim 4 , wherein a first blade cartridge assembly of the pair of blade cartridge assemblies facilitates a 45 degree angle cut in a first direction relative to a cutting surface and a second blade cartridge assembly of the pair of blade cartridge assemblies facilitates a 45 degree angle cut in a second direction relative to the cutting surface.
12 . A foam board cutter comprising:
a body member comprising:
a first housing shell and a second housing shell, the first housing shell and second housing shell each comprising a slider button track having a slot with an interior boarder that includes a plurality of notches;
an intermediate member disposed between and configured to support connection of the first housing shell and the second housing shell, the intermediate member comprising a first face facing the first housing shell and a second face facing the second housing shell, the first face and the second face each comprising a blade cartridge assembly groove;
a first gap between the first face of the intermediate member and the first housing shell;
a second gap between the second face of the intermediate member and the second housing shell, wherein the first gap and the second gap each define an opening in a rear portion of the body member; and
a removable end cap configured to selectively attach to a rear end of the body member to cover the first gap and the second gap; and
a pair of blade cartridge assemblies, wherein one blade cartridge assembly of the pair of blade cartridge assemblies is removably disposed in each of the first gap and the second gap, each of the blade carriage assemblies further comprising:
a slider button assembly comprising a base plate adapted to engage a slider post of a slide button adapted to travel along the slot of the slider button track, the base plate having a shaped member with at least two notch engagement ends, each notch engagement end of each slider button assembly configured to be selectively received by the notches of its respective slider button track to selectively lock each slider button assembly in a selected position relative to its respective slider button track; and
a blade holder extending from an end of the slider button assembly and configured to retain a blade.
13 . The foam board cutter of claim 12 , wherein a first blade cartridge assembly of the pair blade cartridge assemblies is configured to travel within the first gap along a first blade cartridge assembly groove on the intermediate member and a second blade cartridge assembly of the pair blade cartridge assemblies is configured to travel within the second gap along a second blade cartridge assembly groove on the intermediate member.
14 . The foam board cutter of claim 12 , wherein the blade holder comprises a first arm extension comprising one or more “u” shaped protrusions and a second arm extension comprising a cylindrical protrusion configured to be received in a receiving hole of the blade.
15 . The foam board cutter of claim 12 , further comprising a lifting tool on a front end of the intermediate member.
16 . The foam board cutter of claim 12 , wherein each slider button assembly further comprises:
a pair of wing elements extending from opposing side surfaces of the slider post; and
a shaped opening in the base plate;
wherein the shaped member is a wide “u” shape and comprises a pair of arm elements extending from a flexible base portion which extends from a surface of the base plate, each arm element comprising at least one notch engagement end, and wherein at least a portion of the shaped member configured to be received by the shaped opening.
