This listing is for a vintage advertising pocket knife multi-tool keychain (specifically part of the famous "Trim Trio" line or similar promotional models manufactured by Bassett). It functions as a folding pocket knife, a bottle opener, and features a flathead screwdriver/scraper tip. The text on the tool reads "Amery Telephone Co. - Amery Wis". The Amery Telephone Companygotits start in 1897 when three local businessmen established telephone service for the Amery, Wisconsin community. The company has evolved significantly. They changed names to Amery Electric Co. in 1902, went back to Amery Telephone Co. in 1944, and became Amery Telcom, Inc. in 1989. Today, they operate under the unified name Northwest Communications, providing modern fiber-optic internet, phone, and cable services to the region. The tool is manufactured by the W.E. Bassett Company based in Derby, Connecticut. Founded in 1939, W.E. Bassett is most famous for its "Trim" brand grooming products (like fingernail clippers) and vintage everyday carry (EDC) multi-tools. The text stamped on the blade reads "BASSETT USA PAT D 2779398". U.S. Patent No. 2,779,398 was granted in January 1957 for a combined pocket tool structure. Given the 1957 patent date, the "Amery Telephone Co." name format used on the stamping (which they reverted to in 1944 and kept until 1989), and the style of the promotional engraving, this tool was distributed between the late 1950s and the 1970s.
