An apparatus having a handle with a mounted hand grip is described. A first end wall surface of the hand grip is tapered from a base surface to a top surface of the hand grip. A second end wall surface of the hand grip is tapered from the base surface to the top surface of the hand grip. A first end wall of the recess engages the first end wall surface of the hand grip and prevents movement of the first end wall surface away from the base surface of the recess. A second end wall of the recess engages the second end wall surface of the hand grip and prevents movement of the first end wall surface away from the base surface of the recess.

A kitchen instrument with a replaceable head is described having a handle, an ejection shaft, and an ejection knob. The handle is mostly hollow with an opening on a first side and an opening on the second side opposite the first side. The opening on the first side includes an indent shaped to secure a replaceable head by preventing exiting from the indent and also from rotating. The replaceable head has a connector with a first connecting portion and a second connecting portion shaped to be secured in the indent. An ejection shaft is sized and arranged to be inserted in the second side and pass through the handle. The ejection shaft is sized to press on the replaceable head to eject the replaceable head. Multiple replaceable kitchen utensils in the form of replaceable heads are attachable to the same handle of the kitchen instrument.

A cleaning device and method of cleaning are provided. The cleaning device includes a power source and a pump in selective electrical communication with the power source. A storage container is provided. A valve assembly is disposed in the storage container and in fluid communication with the pump, the valve assembly being configured to selectively flow cleaning fluid from a first portion and a second portion of the storage container. A cleaning element having a spray nozzle is in fluid communication with the pump.

Presented here are toollessly releasable, interchangeable handles for hand tools and methods of use thereof. Hand tool users often experience discomfort and injury because hand tool handles are not well suited to each user's hands. In addition, different hand tools have different handles, so users that switch between hand tools often find a different level of comfort with different hand tools. The disclosed platform for interchangeable handles for hand tools allows a user to attach handles custom fitted to their hand to any corresponding hand tool, and likewise allows different users to share a hand tool by detaching the first user's handles and then attaching a second user's handles. Various embodiments for connecting interchangeable handles to hand tools are shown. Additionally, a fluid reservoir disposed within an interchangeable handle and locking mechanisms for keeping the interchangeable handles attached to the hand tool are disclosed.

A device comprising: (a) a first working arm; (b) a shuttle located on the first working arm, and (c) a bias device; wherein the bias device biases the first working arm when the shuttle is in a first position, and wherein the bias device is free of biasing the first working arm when the shuttle is in a second position.

A striking hand tool includes a grip component where an external surface has a front arc half and a rear arc half, wherein an area of the grip is smaller in a first cross sectional plane further from a head of the tool than a second plane closer to the head portion. A ρ value of the front arc half in the first cross sectional plane is less than approximately 0.45. A measurement from a first axis to a frontmost point in the first cross sectional plane is between 17.5 mm and 19 mm. A ρ value of the front arc half in the second cross sectional plane is less than approximately 0.5. A measurement from the first axis to a frontmost point in the second cross sectional plane is between 18.5 mm and 20 mm. Methods of manufacturing and striking hand tools having desirous durometer measurements are also disclosed.

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 tool joinable with a handle. The tool includes a body, the body includes a middle area configured to be joinable to the handle. The front end of the body includes a toe extending away from the middle area. The toe includes a first vertical thickness and a second vertical thickness less than the first vertical thickness for a length of the toe extending away from the middle area. The back end of the body can include a heal pad extending away from the middle area and to create a heal gap between a bottom surface of the heal pad and the second portion of the bottom edge defined by the middle area. The tool can include a fulcrum joined to the body and defining a fulcrum portion of the bottom edge with the fulcrum projecting away from the top edge.

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 cleaning device and method of cleaning are provided. The cleaning device includes a power source and a pump in selective electrical communication with the power source. A storage container is provided. A valve assembly is disposed in the storage container and in fluid communication with the pump, the valve assembly being configured to selectively flow cleaning fluid from a first portion and a second portion of the storage container. A cleaning element having a spray nozzle is in fluid communication with the pump.
