A hand tool includes a first and a second handles, a rotating locking set, a fastening set, and a spring. The first and second handles include chamfered planes respectively. The rotating locking set includes a rotating block and a locking block. The fastening set includes a stud and a nut. The spring is mounted around the stud and elastically abuts against the rotating block. The first handle or the second handle drives the rotating block to disengage from the locking block when being pulled by an external force. The first handle and the rotating block rotate with respect to the second handle by the stud as the center point. The rotating block and the locking block are locked with each other after rotating a specific angle, so as to position the first handle and the second handle.

A biaxial foldout tool includes a body with opposing ends and one or more sets of tool drivers. The opposing ends are rotated 90 from each other. A first set of tool drivers is positioned on/near a first end and rotates about a first hinge; a second set of tool drivers is positioned on/near a second end and rotates about a second hinge. A first portion of the first set opens in a direction counter to an open direction of a second portion of the first set of tool drivers. A first portion of the second set opens in a direction counter to an open direction of a second portion of the second set of tool drivers. When tool drivers are in an open position, internal stops prevent the tool drivers from opening past a predetermined angle. The tool drivers are contained within channels of the body when in a closed position.

A cutter including a cutting head and an adjustable handle pivotally coupled to the cutting head. The adjustable handle includes a first adjustment assembly to change a length the adjustable handle extends from the cutting head. The adjustable handle also includes a second adjustment assembly to change the position of the adjustable handle with respect to the cutting head.

A palm wrench includes a C-shaped body and a driving head. The driving head is pivotably and rotatably located within the body. The body has an opening, and the driving head has two function ends on two sides thereof. The driving head is pivotably connected to the body by two pivots which extend through the body and are connected to the driving head. The driving head can be rotated with respect to the body, and the user can grapes the body to rotate the driving head to output torque.

A circular, cylindrically shaped tool handle holds multiple sizes of tools. The handle includes one or more holding slots each positioned on the outer surface into which tools are inserted and held. Each holding slot includes one or more contoured compartments in which tools rest when engaged with the handle. Each contoured compartment is of a size and dimension which corresponds to one or more tool sizes. Each contoured compartment is formed about a corresponding receiving hole. A lock is positioned over the contoured compartment to irremovably confine the short leg of the hexagonal wrench within the contoured compartment. Hexagonal shaped tools other than wrenches are able to be used with the handle of the present invention such as screwdrivers and socket wrenches. A tool container stores the tools and the tool handle.

A paint roller includes a paint roller handle coupled to a proximal end of a paint roller frame and a paint applicator positioned on a distal end of the paint roller frame. The paint roller handle includes a first contact member positioned on a distal end of at least one distal frame member, a second contact member positioned on a proximal end of the at least one distal frame member, and a third contact member positioned on a proximal end of at least one proximal frame member. The proximal end of the at least one distal frame member is positioned on a distal end of the at least one proximal frame member.

A rotary wrench includes a first wrench body, a second wrench body, and an elastic member. The first wrench body has a first grip whose one end has a pivot hole. The second wrench body has a second grip whose one end has a pivot axially extending outward. The pivot is rotatably received in the pivot hole of the first grip of the first wrench body, so that the first and second wrench bodies are allowed to rotate with respect to each other and provide adjustable working angles. The elastic member is mounted around the pivot of the second wrench body, and prop between the first grip of the first wrench body and the second grip of the second wrench body, for providing an elastic resistance that holds the first and second wrench bodies in position.

A hand tool assembly includes a rod and a handle which is pivotably connected to the rod, and a control unit which is movable along the rod. When the rod and the handle are located linearly, the control unit is moved to a position where the rod and the handle are secured linearly. When the handle is perpendicular to the rod, the control unit is moved another position where the handle is secured perpendicularly to the rod. The rod and the handle are able to be connected with different hand tools.
