A kit has a handle with first and second handle portions asymmetrically disposed above a pivot. The pivot may be collinear with the first handle portion and connected by an offset leg to the second handle portion. Various instrument arms connected to instrument heads are preferably provided as a kit with the handle. The arms may be sectionally disposed or integral with instrument heads selected from the group of forks, such as meat forks, pasta forks, etc, grippers, spatulas, etc.

A locking clutch ratchet wrench (1) is configured such that a clutch ring (500) forms the mid part of aminate like structure. Under torque applying conditions, the compression forces applied to the clutch ring (500) are substantially dissipated around the circumference (507) of the clutch ring. This inwardly directed force clamp against the inherently strong outer surface (405) of the drive element (400). The resultant pseudo laminate structure of the drive element (400), clutch (500) and housing (201, 202) enables the construction of a proportionately stronger ratchet wrench of reduced height or width.

Provided is a cutting tool with which an operator can cut a to-be-cut material by grasping a second handle while setting a first handle stably, and in which the first handle can be changed from a stably-set mode to a grippable mode as with the second handle. The cutting tool has a sidewardly-protruding extension component disposed at the base end of the first handle, which is installed so that, with respect to a handle main body of the first handle, it can be freely changed between a transverse position substantially aligned with the axial direction of the pivotal shaft and a longitudinal position aligned with the lengthwise direction of the handle main body, and, a position holding mechanism is disposed between the extension component and the handle main body, for holding the extension component in each position.

A ratchet wrench having a flexible positioning structure includes a drive bar, a rotary head, and a locking button. The drive bar includes a fork arm, an axial hole, and a radial hole communicating with the axial hole. The rotary head is pivotally connected to the fork arm; the rotary head includes a round housing, a plurality of positioning recesses disposed on the round housing, and a pivot axis passing through the rotary head and two ends of the fork arm. The pivot axis is perpendicular to the radial hole. The locking button includes a flexible fastener inserted through the radial hole and a latch bar disposed in the axial hole. The flexible fastener is flexibly movable in association with movement of the latch bar, so that the latch bar is engaged with or released from any of the positioning recesses.

A tool assembly includes a first body, a connector and a second body. The first body has a first end and a second end. A slot is defined through the wall of the body and extends from the second end of the first body to the middle portion of the first body. The slot includes a first end having a first connection portion, and a second end having a second connection portion. The connector is mounted to the second body and has an outer threaded section. The outer threaded section is threadedly connected to either the first connection portion or the second connection portion of the first body to locate the first body at different angular position relative to the second body.

A screw bit body which allows for efficient torque force application onto a socket fastener from a variety of angles. The screw bit body includes a plurality of laterally-bracing sidewalls, a first base, and a second base. The laterally-bracing sidewalls are radially distributed about a rotation axis of the screw bit body with each further including a first lateral edge, a second lateral edge, a concave surface, a convex surface, and an engagement cavity. The convex surface is adjacent to the first base and the concave surface is adjacent to the second base to create a ball-like shape. The engagement cavity creates a gripping point to prevent slippage in between the screw bit body and the socket fastener. The engagement cavity traverses normal and into the concave surface and the convex surface. Additionally, the engagement cavity traverses into the screw bit body from the first base to the second base.

A ratchet wrench capable of rotating quickly and driving rotation includes a handle, a rotary head, a positioning mechanism, and a sleeve. The handle includes an arm and a bar body. The bar body includes an accommodating slot; the arm includes a through hole. The rotary head is connected to the arm and includes recess portions. The positioning mechanism includes a positioning element, a resilient body, and a block element. The resilient body receives the positioning element and is received in the through hole, the positioning element is correspondingly disposed in any of the recess portions, and the block element is connected to the positioning element. The sleeve receives the bar body and operably drives the block element to slide in the accommodating slot, so that the positioning element is positioned and selectively engaged with any recess portion.

A multi-purpose hand tool system is described. The tool system includes a handle and one or more inserts that are releasably engaged with the handle. The tool system is useful for a variety of applications including use with basin and faucet hardware.

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 wrench adjustable in head angle includes a pull lever having one end provided with an accommodating groove for receiving a spring and a resisting pin. The resisting pin is fitted thereon with a push member, and the pull lever is pivotally connected with a driving head. The resisting pin has one end elastically pushed by the spring to be engaged with one end of the driving head and the resisting pin is engaged with the push member. The push member can be pushed to actuate the resisting pin to press the spring, letting the resisting pin disengaged from the driving head for adjusting the angle of the driving head, convenient in operation.
