A universal handle attachment tool comprises a body having a plurality of tool sides each having a container interface surface operable to engage a face of a particular container, and having a container handle interface slot operable to receive a handle of the container. The slot can comprise a keyed profile operable to interface and lock the handle attachment tool to the container. The container interface surface extends in opposing directions beyond the slot to facilitate distribution of one or more loads acting between the face of the container and the handle attachment tool to facilitate manipulation of the container. A container for storage of at least one object comprises a container body defined by a plurality of sidewalls, and a recessed portion formed a sidewall defining a recessed cavity. The container has a handle spanning the recessed cavity, whereby the recessed cavity facilitates clearance of at least one finger of a user upon grasping the handle.

A wrench structure includes a main body provided with a drive portion, a shank, a protruding block, a handle, a first connecting portion, and a second connecting portion. The shank has two first faces and two second faces formed on two sides thereof. The protruding block has two third faces and two fourth faces. The handle has two fifth faces and two sixth faces. The first connecting portion has two seventh faces and two eighth faces. Thus, the main body is sequentially provided with the drive portion, the shank, the second connecting portion, the protruding block, the first connecting portion, and the handle. The shank, the protruding block, the first connecting portion, and the handle have different height and width defined therebetween.

A tool includes a handle and a blade. The handle extends from a handle first end to a handle second end. The blade has a first surface and an opposed second surface and defines a cutting edge between the first surface and the second surface. The blade extends from a blade first end to a blade second end. The blade and the handle are rotatably coupled at the blade first end and the handle first end about an axis extending from the first surface of the blade to the second surface of the blade. The blade is rotatable from a first position to a second position. The blade is lockable in the first position. When in the first position, the blade extends out from the handle second end.

A multipurpose extension device for attachment and coupling with hand tools, such as tire irons, ratchets and wrenches. The device is an elongated hollow rigid tube containing a rectangular notch and narrow channel. Inside the hollow rigid tube contains magnetic materials to assist securing of inserted or coupled tool. Two ends to device, one end containing a handle other end is open receptacle. This receptacle end of the device is for the acceptance and coupling with hand tools such as, ratchets, pry bars and various other hand tools. A wrench can be inserted into the device by sliding in then turning 90 degrees to secure. One purpose of this device is to provide increased leverage and length of hand tools, for the removal and installation of threaded hardware. Additional use of this device is to increase leverage on pry bars, in the separation items such as, machinery gears.

A collapsible snow paddle. The paddle includes an elongated handle, a rotatable coupling affixed to one end of the handle, and a generally planar snow remover, the rotatable coupling affixed to a rear surface of the remover so that he remover may be collapsed against the handle for storage and extended transverse to the handle for use. The snow remover may have a scraper edge inclined at an angle relative to the surface of the snow remover for scraping ice and a relatively soft capped edge for removing snow.

In some examples, a multi-device removal and installation tool may include a device removal tool including a first side having a first receiver with a first dimension that removably receives a first device, and a second side having a second receiver with a second dimension that removably receives a second device. The first dimension may be different from the second dimension. A torque limit tool may apply, in a first rotation direction of the torque limit tool and the device removal tool, a tightening torque to the first device. Further, the torque limit tool may apply, in a second rotation direction of the torque limit tool and the device removal tool, a loosening torque to the first device. The second rotation direction may be generally opposite to the first rotation direction.

A safety knife functions as both a box cutter and a separate line cutter. A slidable grip is manually displaceable between two stable safety positions. In one safety position, the grip obstructs access to a forwardly projecting blade. In a second safety position, the grip obstructs access to the line cutter.

Customized assistive gripping devices in accordance with embodiments of the invention are disclosed. In one embodiment, a customized assistive gripping device, comprising a body comprising an outer surface that conforms to an interior contour of a user's hand in a gripping configuration; and a slot located inside the body, wherein the slot comprises a first opening for receiving an object.

Disclosed is a tool, such as pliers, with handle offsets and stop features. In an embodiment, the tool has a minimum of about 0.50 inches of clearance between handles in an area where a user's index finger contacts the handles. This is accomplished by offsetting upper and lower handles of the tool. For example, the lower handle may be offset about 1.10 inches from a pivot point between the handles. Similarly, an end of the upper handle may be offset by about 1.150 inches from the pivot point when jaws of the tool are adjusted to a closed position.
