Strange pliers

[Happygilmore]

Hello, I had a friend buy a different house and previous owner left a bunch of older tools. My friend unloaded boxes upon boxes into my possession. Lucky me !! Quite a few Snap on sockets along with other treasures. By the looks of some of the tools previous owner may have been into HVAC ?? Nippers ,seam tools ,assortment of brass & copper fittings etc. But there’s a pair of pliers like I have never saw before hoping someone out there will recognize them ? They have a pin extending from the pivot, one jaw has a curved cut out and the opposite jaw has a brass piece that swivels located on the back side of the jaw. They’re about 4 3/4” long the only identifying mark I could find actually spelled nothing decipherable!! Best I can see is DLHJGONICT TISSOI Anyone have any idea what these pliers are used for ? Thank you Happy

^ I am not seeing anything like that in the photo images.

Image is too dark. Not clear enough to make out detail.

Best wild guess: French.

My memory is not what it used to be, but I do remember seeing some pliers used by the watch maker, with that name over 50 years ago.

Thanks to everyone for the info. Guess you never know what you may find in the bottom of a box of “ Treasures “ !!

Maybe a tool to install a press-fit watch back onto the watch body rear? The pivoting piece allows for parallel jaws so the watch back is evenly-pressed into place. My guess.

Yep, them's some strange pliers.

KnurledNut's post has a very interesting history. Tissot seems to be the last link to the Hugoniot era of watchmaking.

Google photo look up + AI:

This is a pair of vintage round-nose pliers used for bending and looping wires.

• Both jaws are round and taper from the pivot to the tip.
  
  
• They are ideal for creating loops, jump rings, and clasps, particularly in jewelry making and crafts.
  
  
• Historically, similar tools were used by electricians to form loops (lugs) on solid electrical wire to fit under screw terminals.
  
  
• The tool appears to have a lap joint and a simple design, suggesting it is a classic or antique piece.

^ Please don't spread "AI" misinformation on vintage tools here. Google's "AI" and ebay's "AI" have demonstrated themselves both to be mind-bogglingly inaccurate with their crazy wild guesses. "GROK" has demonstrated itself to be no better.

Lucien Hugoniot-Tissot made tools for watchmakers - a very specialized and narrow market niche, having absolutely nothing to do with "jewelry", "crafts" or "electricians". To even suggest the association is evidence in and of itself "AI" simply doesn't know what it's talking about and is just making **** up that sounds plausible to the unknowing.

Thanks.

Ultimate All-Time "AI" FAIL

Especially considering that the AI description--of what I'd call chain pliers--isn't vaguely close to what they look like.

They have a pin extending from the pivot,

First thing I zeroed in on when a little birdy told me about this thread! I love that idea! I can see how an offset handle could be very helpful from time to time even for other kinds of pliers with more practical purposes.

I'm no watchmaker, but I have two pairs of Hugoniot-Tissot pliers that I like to use like small intricate hand vises any time I need a small intricate hand vise. Ironically, I also have an actual Hugoniot-Tissot hand vise. Smartly, the handle ring on the large pliers is interchangeable
with the hand vise.

These are fine, well-made tools often bearing not only the Hugoniot-Tissot logo, apparently illegible on your example, but also an "ACIER FONDU" marking, which has nothing to do with the dippable Swiss melted cheese and wine culinary goop, but means "CAST STEEL" in French.

 

[KnurledNut]

Um no, AI, that's definitely a box joint not a lap joint.

 

[neophyte]

The smaller plier with the box joint and post sticking out of the side looks similar to some “Bow Closing Pliers”, but that is a guess.
The side post could be for bending thin wire, or possibly used for mounting the plier to a bench fixture so both hands are free while getting whatever item is being worked on in place.
I suspect the latter.
Bergeon no longer has something similar in their catalog that I saw, unless listed under something other than “pliers”.
I syspect to identify the type of tool, it might be necessary to look thru a 100+/- catalog from a company like Grobet that sold fine jewelers tools.

I tried the many page Benj Allen at ITCL, but didn't see it under pliers.

I didn't see them under vise, wire benders, etc either.
