Manufactured by A. M. Hexdall Co. - Morris IL

"The invention relates to hand hammers generally, and more particularly to an improved hammer for sheet metalworking. The general object of the invention is to, provide a hammer especially suited for the various operations, involved in the fabrication and erection of sheet metal structures and which is constructed so as to afford a feeling of balance and a resiliency or bounce that makes it easier and less fatiguing in use. A more specific object is to provide a hammer particularly well adapted for completing Pittsburgh joints in sheet metal structures, which can be used effectively in confined spaces and which is universally adaptable for seating the driven flanges of either right or left-hand joints or other joint finishing operations such as the lapping over of the second or locking flange." A family member "reminisce" explains the origin of the tool. Trade journal listings show Hexdall marketing the hammer.

Manufactured by Hi-Tech Company - Kerrville TX

Latch mechanism for "snap-ring pliers" based on patent no. 4,280,265. "A convertible retaining ring pliers includes a pair of jaws and a pair of handles all rotatable independently about a common pivot. Each jaw includes a transverse bore spaced from and parallel to the pivot axis for receiving an elongated cylindrical latching pin. Each handle has an associated end plate disposed on one side of the jaws, the end plates having holes to selectively receive an end of a latching pin to selectively latch a jaw to a respective handle. The latching pin bores have elongated grooves and the latching pins have associated friction springs with projecting tabs coacting with those grooves to retain the pins within the assembled pliers. Elongated retaining ring tips have hexagonal shanks received in multi-sided jaw recesses to retain the tips against rotation and to enable selected rotational orientation of the tips. The convertible pliers includes a ratchet mechanism operative between the two handles to maintain the handles closed in a selected position against the load of the retaining ring." Both patent numbers appear on pliers produced by Hi-Tech Co. (Kerrville, TX).
