A utility knife is disclosed, including a housing having a handle portion and a front end. A first wing and a second wing are each pivotally engaged with the handle portion. The first wing and the second wing guide at least one blade along an edge of a box when cutting and disassembling the box. A trigger extends and retract the at least one blade such that the blade(s) are only extended during use to protect the user.

A removable attachment assembly for a ninety degree drill assembly, which includes a base member and a securement assembly secured to the base member for releasably securing the base member to a housing of the ninety degree drill assembly. The removable attachment assembly further includes a cushion member releasably securable to the base member.

A railroad brake stick can include: a head having a planar shape with a recesses and/or protrusions on one or more side surfaces of the planar shape, the planar shape having a head interlocking groove on a hilt region; a cross-support having a planar shape with a support interlocking groove interlocked with the head interlocking groove such that the planar shape of the head crosses with the planar shape of the cross-support to form an interlocking region; and a handle coupled to the head and cross-support such that the interlocking region is within an end of the handle. In some aspects, a cover is over the handle. n some aspects, the head is a composite material and the cross-support is a composite material and the handle is a composite material.

A utility knife includes a body having a front end and a rear end opposite the front end. A blade holder, supported by the body, is moveable relative to the body, to move a blade between an extended position and a retracted position. The blade extends through a blade aperture when in the extended position. The blade aperture is sized to receive a hook attached to the blade of a tape measure.

A tool system includes a magnetic tool base; mounting handles, each with an inner magnet and a lower magnet; interchangeable tool portions, each detachably attachable to a mounting handle; such that an interchangeable tool portion and a mounting handle form an assembled tool that is held together by the inner magnet, and such the assembled tool is secured in an upright position on the magnetic tool base by the lower magnet.

An ergonomic manual driver includes a handle having ergonomic recesses. A manual driver includes a shank and a handle attached to the shank. The handle includes a proximal portion, a middle portion, and a distal portion. The distal portion has a distal portion distal end cross section that includes polygonal perimeter line segments joined by intervening perimeter segments. The distal portion has a distal portion proximal end cross section that includes polygonal perimeter line segments joined by intervening perimeter segments. Orientations of the polygonal perimeter line segments of the distal portion distal end are offset rotationally by 15 degrees to 45 degrees around the shank axis relative to the polygonal perimeter line segments of the distal portion proximal end. The distal portion comprises distal portion recesses, which extend from the distal portion proximal end to the distal portion distal end.

Demolition tools are presented including: a handle having a proximal end and a distal end; a prying head disposed along the distal end of the handle, the prying head including at least two tines mechanically coupled with a substantially cylindrical cross frame, where the at least two tines each includes: an upper surface forming a width, a proximal end and a distal end; a tapered base including a first end forming a profile complementary to the substantially cylindrical cross frame, the tapered base mechanically coupled to the cylindrical cross frame at the proximal end of the upper surface along the profile, the tapered base tapering upward towards the upper surface from the first end towards the distal end of the upper surface, where the at least two tines each form a fulcrum point where the tapered base is coupled with the cross frame.
