Craftsman's angle-nose gripping pliers were a style of slip-joint pliers with an angled head and three adjustment positions.
The catalogs typically referred to these as "Universal Pliers", although the description sometimes changed from year to year.
The top inset shows a side view of the pliers, illustrating the "Nested Diamonds" gripping pattern on the handles.
The small inset shows a close-up of the "41AM" code stamped on the underside of one handle.
The marked model number is rare for Craftsman tools of this era.
The Craftsman model 5797 pliers had been discontinued by 1935, providing a bracket for the manufacturing dates for this model.
The Craftsman name in block text and the model number marking suggest an earlier date within this range. 188 shows a pair of Craftsman Vanadium 6.5 inch slip-joint combination pliers, stamped "Vanadium" below the Craftsman underline logo, and with a "41AM" code on the underside of one handle (see inset).
The overall length is 6.5 inches, and the finish is polished nickel.
The 1938 Craftsman tool catalog has very clear illustrations of the "Nested Diamonds" pattern, and later Craftsman tool catalogs show that this pattern remained in use through the 1950s, and into the 1960s for at least some models.The slip-joint slot provides circular openings for three adjustment positions. The finish is polished steel with no plating, which together with the double-line logo suggests a manufacturing date around 1945. Sears first offered Craftsman Button's pliers in the fall of 1930, but had previously sold them under the Fulton brand.Note that the front edge of the slot is flat, with the circular openings positioned on the opposite side. 190 shows another similar pair of Craftsman Vanadium 8 inch slip-joint angle-nose gripping pliers, stamped "Vanadium" below the Craftsman underline logo. Button's pattern pliers have a long and interesting history going back well into the 19th century. Button's pliers were initially available in sizes 6, 8, and 10 inches.The overall length is 8.3 inches fully extended, and the finish is polished nickel.The top inset shows a side view of the pliers, illustrating the "Nested Diamonds" gripping pattern on the handles. By the early 20th century Button's pliers were being made by a number of companies, including Kraeuter and Utica.
Currently we don't have a catalog reference for these pliers.
