ABSTRACT:
This tested invention, for use with an unmodified hammer (402), is a simple attachment (31) whose fastener-receiving region (57), and fastener-holding apparatus (54), along with a magnetism and support extender (542), allow safe, one-handed starting of a wide range of size and types of fasteners (562), including nails, screws, tacks, and staples. With the attachment, a fastener can be easily started with the usual initial hammer swing and then driven to the desired depth by striking it with the hammer face in the conventional manner with an unbroken rhythm. The attaching mechanism (72) enables attaching to and detaching from a hammer with only one hand. Spacers (202), or tailor forming of the attachment body (32), allow it to fit all of the common household hammers. Alternative holding fingers (314, 316, 318FIG.20) handle nonmagnetic fasteners.
