I recently found this pair of duckbill pliers at a yard sale. They're marked "L. Huggniot-Tissot." I can't make out what the logo on the left side is supposed to represent. I've read that the company's trademarks included a crown, a lion (passant, looking over shoulder), a cockerel and the letters "L.H.T." It doesn't look to me like any of these.
Curiously, it's marked "Acier Anglais" ("English steel") but also "Made in France." A truly bilingual tool.
There's not a lot of online information about this manufacturer. I did discover that Lucien Hugoniot-Tissot manufactured a variety of watchmaker’s, jeweler's and watchmaker's tools. The company was located in Montécheroux in the Bourgogne-Franche-Comté region of eastern France near the border with Switzerland and was active between 1850 and 1930. How the tool ended up in the boonies of eastern Ontario will remain a delicious mystery.
