A punching and stamping tool and a fastening device for using this tool is disclosed. The punching and stamping tool comprises a driving mechanism which moves an upper tool section, having a die, towards a lower tool section, having a punch, to punch at least a pair of angled hooking cuts into two metal bands, such as the overlapping ends of a strap wrapped around a package. The angled hooking cuts effectively fasten the bands together. The driving mechanism comprises a cam, which moves the upper tool section to a set position where the upper tool section is a distance from the lower tool section approximately equal to the thickness of the bands. The driving mechanism also comprises an eccentric shaft having a throw which acts on the upper tool section to punch the angled hooking cuts into the bands.
