Tool adapter assemblies are presented including: a quick release coupler including: a spindle defining a partial cylindrical cavity, the spindle including a base portion, a body portion, and an end portion where the body portion includes a number of ball stop recesses; a number of ball stops slidingly engaged with the number of ball stop recesses; and a sleeve slidingly coupled with the spindle, where the sleeve is configured to lock and release the ball stops; and an accessory connector including at least one of: one or more annular grooves configured to engage with number of ball stops, a number of detents configured to engage with number of ball stops, or both the annular groove and the number of detents; and an accessory engagement portion positioned along a proximal end of the accessory connector.

A knife includes a body that includes a handle section, a substantially circular blade housing section, and a blade including a cutting edge having substantially the same radius of curvature of the blade housing. The substantially circular blade housing section extends substantially perpendicular from the handle section. The blade extends longitudinally out of the blade housing at a position substantially 180° away from the position of the handle section along the circumference of the blade housing and terminates in a sharp point. The width of the blade at the portion immediately adjacent to the blade housing and opposite the blade point is substantially equal to the diameter of the blade housing.

A conduit reamer with a lanyard receiver, inner and/or outer cutting blades is provided. The lanyard receiver is located along an axis of the handle near the tool's center of gravity. For example, the lanyard receiver is located between the handle and a bit retainer near the center of gravity. In this orientation, the lanyard receiver prevents tipping of the conduit reamer and retains the bit within the bit retainer when the conduit reamer is dropped. The inner and outer cutting blades include an acute angle that is between 45 and 90 degrees to deburr an end of a conduit.

Compact hand axe that can chop along multiple axes is disclosed. While utilizing the tool in the hand axe configuration the forward-facing, mid-grip trigger allows for axial rotation to occurs in user's hand around the middle finger, enabling it to achieve a far greater edge velocity/impact than would ordinarily be expected from a blade of this length. Furthermore, working in conjunction with the channeled mounting wedge, the trigger also enables the present hand axe to be mounted securely to a haft of the users choosing so that the tool's broad front edge can provide the functional yield of a full-size, dedicated axe.

A starter handle gripping device includes a hand grip having a width that is suitable for receiving a human hand, a pair of elongated arms that extend from both ends of the handle and a coupler for engaging the starter handle. The hand grip, arms and coupler include a one-piece construction, and the arms are diagonal in relation to the handle. The coupler includes a pair of generally U-shaped fingers that are integrally formed onto the ends of the two elongated arms, and a cross member for maintaining a separation distance between the ends of the arms. The second end of each of the arms includes a separation distance that is complementary to a width of a cord cavity of the starter handle, and each of the fingers includes a width that is complementary to a thickness of the upper portion of the starter handle.

In one example, a system includes a hammer extender having a head formed from an upper layer, a lower layer and a side layer. The hammer extender includes an elongated body portion having a solid core elongated portion and a hollow core elongated portion. One end of the solid core elongated portion is connected to the head, and the other end is connected to the hollow core elongated portion. The hollow core elongated portion can receive and guide a nail during impact. The system may include a hammer having a hammer handle with a hollow interior to store the hammer extender.

An adapter comprising a handle assembly and connector is disclosed that can be securely attached to single handle household device, such as a vacuum cleaner. The adapter once attached assists individuals with the operation of the household device.
