The trade mark "Hammer Brand" logo was adopted in 1878 by the New York Knife Company. The words "Hammer Brand" were added to the now famous arm and hammer logo in 1882. In a 1908 catalog, the tang stamp on every illustrated knife blade was New York Knife Co. Walden and only Hammer Brand blade etches. It appears the Hammer Brand tang stamp on one blade and New York Knife Co. Walden on the other appeared after 1908 to me ...................... unless they were using outdated illustrations in the 1908 catalogs, of course.
There are numerous arched as well as straight line tang stamps illustrated in that 1908 catalog.
I suspect the pearl small congress shown above might pre-date the Hammer Brand era. Find me a faint Hammer etch on that one and prove me wrong !
My first NYKC Hammer Brand knife was put to good use by someone. All blades still snap open and shut though. :
