A tool includes a handle, and arm, a pivotable coupler, and an implement. The handle has a first end and an opposing second end. The arm has a third end and an opposing fourth end. The pivotable coupler couples the opposing second end of the handle to the third end of the arm. The handle and the arm are pivotable relative to each other about the pivotable coupler between a closed orientation and an open orientation. The handle and the arm extend in a substantially same direction when arranged in the closed orientation. The arm extends at an angle from the handle when arranged in the open orientation. The implement is coupled to the opposing fourth end of the arm.

Disclosed embodiments include a two-shafted multi-tool including a primary shaft having a D-handle at one end and a releasable tool connector at the opposite end, and a secondary shaft having a D-handle at one end and a rotating connector at the opposite end, and wherein the rotating connector couples the secondary shaft to the primary shaft substantially adjacent to the releasable tool connector. Further disclosed embodiments include at least one adjustable shaft handle that is releasably couplable to either the primary shaft or the secondary shaft.

A quick connect tool interface system including a tool handle component including a handle body with a tool shank engagement section at an end thereof, wherein the tool shank engagement section includes a shank cavity and a coupling button. The tool handle component is arranged for reversible engagement with a farming or landscaping tool implement with a tool shank having a tool shank modification, wherein the tool shank modification includes a button connector. The coupling button of the tool handle component is spring-loaded and configured with a shank retention bar arranged for reversible engagement with the button connector of the tool shank modification, which may be a slot or a notch but not limited thereto.

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.

A hammer tool includes a head and a handle coupled to the head. The handle has a first and a second connecting end fixed to the head. The handle has a first and a second medial section and the first and the second connecting ends extend from the first and the second medial sections respectively. The first and the second medial sections are disposed side by side. The first and the second medial sections form at least one first and at least one second curved sections respectively. The at least one first and the at least one second curved sections abut against each other.

In order to provide a working machine capable of suppressing an increase in size, a working machine that rotates a working tool with motive power of a motor includes a transmission mechanism that transmits a rotational force of the motor to the working tool, a front case in which the transmission mechanism is disposed, a holding tool that is attached to the front case so as to protrude from an outer surface of the case and is gripped by a worker, and an attaching hole which is provided in the front case and to which the holding tool is attached, and the attaching hole penetrates the front case in plan view intersecting with an axis that is a rotation center of the working tool.

A power tool comprises an adjustable auxiliary handle assembly that facilities safe use of the tool by the operator when handling heavy duty handheld machinery. The adjustable auxiliary handle assembly comprises a strap, a handle base, an over-center linkage assembly, a locking lever, a locking lever and an adjustable knob. The strap is easily released and able to rotate and be locked in a different position convenient and comfortable to the operator. The auxiliary handle assembly is adjustable and can be operated with one hand (e.g., one-handed operation). The over-center linkage assembly holds the auxiliary handle position in place while allowing the power tool to be used in high-torque/high load applications.
