A hand held planishing hammer is provided that includes a power unit mounted on a base plate with a handle and powering means that is controllable to produce a hammering action by a combination of a hammer head and slapper to provide flattening, smoothing, and polishing of sheet metal for the aircraft, automobile collision repair, restoration and architectural sheet metal industries.

A paintless dent repair kit includes a housing with a handle extending therefrom and a toothed wheel rotatably retained in the housing. The toothed wheel has a plurality of teeth extending outwards therefrom and is configured to receive, replace, and removably retain any one of a plurality of sockets fixedly attached to one of several dent removal tool tips. The housing features a first button connected to a teethed lever slidably positioned to be either engaged or disengaged with the plurality of teeth of the toothed wheel depending on the position of the first button. Unless the first button is depressed, the dent removal tool is configured to securely and fixedly retain the dent removal tip to facilitate direct transmission of force and torque from the handle to the dent removal tip during dent removal operations. The housing further features a second button attached to a release pin slidably positioned inside the toothed wheel. Pushing n the second button releases the socket and allows for a rapid exchange of the tool tip.

The present invention provides a means to achieve enhanced control of repair forces in the automotive body repair industry. In particular, the present invention provides a modified slide hammer and a method to achieve repair through the controlled application of forces otherwise not attainable with existing embodiments. Additionally, the present invention provides an ease of use and versatility of application and mounting at the site of the work in conjunction with and in line with existing devices used in the repair process. The application of the present invention provides increased reliability in the delivery of intended forces at the site of the work. Further, the inherent isolation of repair forces to the intended site of the work by the use of the present invention reduces the likelihood of secondary damage, material waste, or catastrophic failure thereby also enhancing the safety of the operator and the effectivity of repair. Specifically, the present invention may be implemented in conjunction with existing frame pullers in the automotive body repair industry to affect repair while providing facility to avoid obstructions in the path of applied forces.

An apparatus for modifying a defect in a surface may include a hollow shaft including a first open end and a second open end opposite the first open end, a plunger slidable within the hollow shaft and extending from the first open end, a driver coupled to the second open end of the hollow shaft and extending from the second open end, and a passive resistance mechanism coupling the plunger to the hollow shaft. The passive resistance mechanism biases the plunger towards the second open end of the hollow shaft. The plunger has markings thereon that are visible when the plunger is extended from the first open end. Methods for using the apparatus to modify a defect in a surface are also described.

A punch tool includes a body having a contoured profile configured for holding in a user's hand. The body includes at least one opening for receiving a user's digits and the contoured profile has at least one extension configured for contact with another of the user's digits. A strike portion for applying an external force is located at an upper portion of the body centered on a force line extending through the body. An impact portion is located at a lower portion of the body concentric with the force line and has an end tip configured to focus at least a portion of the external force to a work surface.

The present invention relates to a tool (1) comprising a handle element (101), a rod (103) which is firmly received in the handle element (101) and has a second stop (103a) at its end opposite the handle element (101), a weight (105) slidingly guided on the rod (103), which has a third stop (105a) on its side facing the handle element (101) and a fourth stop (105b) in its interior,
wherein the handle element (101) has a first stop (101a) at its end facing the weight (105), so that the weight (105) can be struck with its third stop (105a) against the first stop (101a) and alternatively with its fourth stop (105b) against the second stop (103a).
