THE ATHA TOOL CO. AND ATHA NAIL HAMMERSThe Atha Tool Co. - located in Newark, New Jersey - was founded in 1884. The Company manufactured and supplied to the blacksmith, railroad maintenance, farrier, automotive repair, machinist, bricklayer, stone cutter and various woodworking trades a wide range of metal and woodworking hand tools - hammers, cold chisels, punches, anvil inserts, sledges, tongs, wedges, forming tools, hatchets, et al. The company established an enviable reputation for design excellence and superior quality and their tools were in great demand especially by blacksmiths. The Atha Tool company - along with their entire line of tools - was acquired by Stanley in 1913, a tremendous addition to the latter company's tool offerings. It appears that at first the Atha Tool company operated independently from the Stanley company and separate catalogs were issued bearing their name. However, in the 1920s Atha tools were gradually incorporated into the Stanley catalogs and the tools were identified as Stanley-Atha throughout the 1920s and 1930s.
Atha nail hammers produced prior to the 1913 Stanley acquisition are stamped on the left cheek of the nicely finished and polished heads with the company logo - an upside down horseshoe with a capital letter A in the center. These Atha nail hammers featured lacquer finished straight grain light colored hickory handles as did subsequent Stanley-Atha hammers.

STANLEY-ATHA NAIL HAMMERS - 1920s TO PRE-WWII 1940sThere was a bewildering succession of model designations and numbering systems - including numerous prefixes and suffixes - for these hammers that was constantly changing during their early production life so I will keep the designations here quite general. The entire numbering system was changed in 1933.
All Stanley-Atha hammers were stamped on the left cheek of the head with the familiar STANLEY within a cartouche logo - sometimes MADE IN USA stamping was appended although this was inconsistent. This variance is also found in catalog illustrations although it should be noted that those illustrations do not always depict actual production tools. There was no Atha stamping on Stanley-Atha hammer heads. Informational decals were affixed to the handles of all new Stanley-Atha hammers - and they are very important identifiers that should be preserved at all cost - even fragments of them - for it is the only way to positively identify Stanley-Atha hammers! Handles were of straight grained hickory and were lacquer finished. The factory applied handle decals soon wore off with use, but the presence of even scant remnants is testament to the originality of handles. The model number, configuration and head weight were often stamped in black ink on the end of the handle - invaluable information all to often lost due to hammer usage. The presence of the distinctive Stanley factory head securing wedges is a good indicator of originality.

Stanley-Atha tack hammers were sometimes employed by wood workers for fine finishing work including installation of leather or fabric coverings. I have included one here in order to illustrate various Stanley-Atha hammer features.

STANLEY NAIL HAMMERS - POST WWII 1940s TO THE 1950sPost-WWII Stanley nail hammers bore different handle decals than the pre-war Stanley-Atha hammers. The first ones following the end of the war and until circa. 1950 were orange colored and bore a small Atha Tool Company logo on the right
All post-WWII Stanley nail Hammers were designated as such in the Tool catalogs and sales literature - there were no longer any Stanley-Atha references. The familiar STANLEY within a cartouche logo continued to be stamped on the left cheek of the head with MADE IN USA sometimes appended, although this was inconsistent as was a model number, configuration and head weight stamping.
StampingsExample of a typical head stamping:

STANLEY
(in cartouche)
No. 51½ 16-OZ
# 5 configuration: bell face - round black neck - polished round poll
W/L code 1½: Head weight: 16 oz. - Overall length: 13"
It seems that Stanley changed the style and form of the stampings from time to time. There are variances similar to those found on Stanley wood chisels. I have encountered hammers of this period with only STANLEY (in cartouche) or STANLEY (in cartouche) with MADE IN USA underneath. These variances can also be found in catalog illustrations although it should be noted that those illustrations do not always depict actual production tools.
DecalsDecals, which sometimes included information relating to features and configuration, were affixed to the handles of new hammers - and sometimes to the right cheek of the head - at the factory.
HandlesHandles were of straight grained hickory and were lacquer finished. The factory applied handle decals soon wore off with use, but the presence of even scant remnants is testament to the originality of handles. The model No. configuration and head weight were usually stamped in black ink on the end of the handle - invaluable information all to often lost due to hammer usage. The presence of the distinctive Stanley factory head securing wedges is a good indicator of originality.

There was also a "semi-ripping" style offered that had slightly more curvature than the standard Ripping Claw depicted.
Stanley Nail Hammer Configurations 1 ..... bell face - round ribbed neck and poll - highly polished - 100 Plus
2 ..... same as 1 except ripping claw instead of curved - 100 Plus
3 ..... bell face - octagon black neck - octagon poll - highly polished
4 ..... plain face - plain neck - highly finished
5 ..... bell face - round black neck - polished round poll
9 ..... plain face - plain neck
10 ... bell face - round black neck with polished ribs - polished round poll
Those models described as having black (enamel paint) necks inevitably came with the tops and bottoms of the heads and the backs of the claws also painted black. The paint on the necks in particular often gradually wore off with heavy use and in consequence was sometimes sanded off entirely by users for a better appearance. "100 PLUS" hammers were described in some 1930s catalogs as having "orange enamel painted head ribs", however, I have only encountered red painted ribs.
