the slap hammer comprising a tool body and a mass translatable on the tool body, wherein the tool body includes an end opening configured to releasably receive the distal end of the shaft, wherein the end opening includes a bottom wall, and an opening transverse to and intersecting the end opening, and wherein the tool body includes one or more orientation features adapted to engage the shaft and orientate the tool body in one or more fixed orientations relative to the shaft;

a push button slidable within the opening between a locked position with the shaft and an unlocked position with the shaft; wherein

the push button includes one or more protrusions adapted to engage the shaft in the locked position and disengage from the shaft in the unlocked position, and wherein the one or more protrusions include one or more cam surfaces positioned proximal the end opening of the tool body;

wherein at least one protrusion includes a distal free end, wherein the distal free end includes at least one concave wall recessed between opposing remaining portions of the distal free end of the at least one protrusion; and

wherein the tool allows for forward impaction and backward impaction of the shaft of the implement, wherein backward impaction transmits force between the at least one concave wall and the opposing remaining portions of the distal free end of the at least one protrusion and the axial facing surface of the shaft, and wherein forward impaction transmits force between the distal end of the shaft in contact with the bottom wall of the tool body end opening.

2. The combination of claim 1 further comprising a biasing member positioned between the push button and the tool body.

3. The combination of claim 1 wherein the push button includes an internal cavity, the internal cavity includes the one or more protrusions projecting inwardly therefrom.

4. The combination of claim 1 further comprising a sliding engagement between the push button and the opening of the tool body, wherein the sliding engagement is one or more pin and slot engagements, wherein at least one pin and slot engagement of the one or more pin and slot engagements includes a pin and a slot, wherein the pin extends through a through opening extending from an exterior wall of the tool body to an interior wall of the tool body to project inwardly into the opening and into the sliding engagement with the slot within an exterior periphery of the push button.

5. The combination of claim 4 wherein the opposing remaining portions are perpendicular to a sliding direction of the push button in the sliding engagement with the opening of the tool body.

6. The combination of claim 1 wherein the at least one concave wall of the one or more concave walls engages an outer diameter of the shaft when in the locked position and the opposing remaining portions of the distal free end are disengaged from the outer diameter of the shaft when in the locked position.

7. The combination of claim 1 wherein the opposing remaining portions of the distal free end are not arcuate in shape.

8. The combination of claim 1 wherein the opposing remaining portions of the distal free end are parallel to each other.

9. A combination of a slap hammer tool having a securing mechanism for attaching a shaft of an implement to the tool, the combination comprising:

the implement having the shaft; and

the slap hammer comprising a tool body and a mass translatable on the tool body, wherein the tool body includes an end opening configured to releasably receive the shaft, and an opening transverse and intersecting the end opening, and the end opening includes one or more orientation features adapted to engage the shaft and orientate the tool body in one or more fixed orientations relative to the shaft;

a push button slidable within the opening, wherein the push button translates between a locked position with the shaft and an unlocked position with the shaft;

wherein the push button includes an internal cavity and one or more apertures within in an exterior periphery, the internal cavity includes one or more protrusions projecting inwardly therefrom;

one or more biasing members positioned between the push button and the tool body thereby urging the one or more protrusions inwardly towards the shaft to the locked position, wherein the one or more biasing members is a spring having opposing ends, and wherein one end of the opposing ends is received by the one or more apertures within the exterior periphery of the push button and the other end of the opposing ends engages an interior wall defining the opening; and

a sliding engagement between the push button and the opening of the tool body, wherein the sliding engagement is two opposing pin and slot engagements, wherein each of the two opposing pin and slot engagements include a pin and a slot, wherein the pin extends perpendicular to a longitudinal axis of the shaft through a through opening extending from an exterior wall of the tool body to an interior wall of the tool body to project inwardly into the opening and into the sliding engagement with the slot within an exterior periphery of the push button.

10. The combination of claim 9 wherein the one or more protrusions include one or more cam surfaces positioned proximal the end opening of the tool body.

11. The combination of claim 9 wherein the internal cavity is a through opening, wherein the through opening is defined by a substantially arcuate wall with the one or more protrusions projecting inwardly into the through opening from the arcuate wall.

12. The combination of claim 9 further comprising one or more cleaning ports extending from an outer wall of the tool body to an inner wall of at least one of the end opening and the opening of the tool body.

13. The combination of claim 9 wherein the one or more protrusions is proximal a bottom wall of the opening.

14. The combination of claim 9 wherein the one or more protrusions includes one or more arcuate walls at a distal free end spaced from the internal cavity and adjacent the shaft.

15. The combination of claim 9 wherein the one or more protrusions includes a planar surface opposite a cam surface of the one or more protrusions.

16. The combination of claim 15 wherein when in the locked position, the planar surface contacts and restricts axially removal of the shaft from the end opening of the tool body.

17. A combination of a tool having a securing mechanism for attaching a shaft of an implement to the tool, the combination comprising:

the implement having the shaft, wherein the shaft includes an annular groove and one or more first flats on opposing axial sides of the annular groove; and

the tool comprising a tool body and a mass translatable on the tool body, wherein the tool body includes an exterior wall, interior wall, and an end opening defined by the interior wall adapted to releasably receive the shaft;

a push button having a biased retention feature;

wherein the biased retention feature includes a retention abutment surface opposite a cam surface, wherein the retention abutment surface interferes with the axial removal of the shaft from the tool body and the cam surface translates the biased retention feature outwardly allowing insertion of the shaft;

a pin and slot engagement allowing translation of the biased retention feature into and out of engagement with the shaft, wherein the pin and slot engagement includes a pin and a slot, wherein the pin extends through a through opening extending from the exterior wall of the tool body to the interior wall of the tool body to project inwardly into sliding engagement with the slot within an exterior periphery of the push button; and

wherein the end opening of the tool body includes one or more second flats on opposing axial sides of the push button, wherein the one or more first flats of the implement shaft engage the one or more second flats of the tool body end opening to orientate the tool body in one or more fixed orientations relative to the shaft of the implement.

18. The combination of claim 17 wherein the retention abutment surface is substantially planar.

19. The combination of claim 17 wherein the biased retention feature includes a concave distal free end between the cam surface and the retention abutment surface.

20. The combination of claim 17 wherein the retention abutment surface contacts from an outer diameter towards an inner diameter of an axial facing planar surface of the shaft and interferes with the axial removal.
