What is it??

[blackoak]

Had these for several years and never could tell what they were used or designed for.

Kitchen tool? Combination utility shears and bottle openers?

[mvwcnews]

I've seen examples before -- no markings, and the sizes of the openings are too small for most kitchen applications.  An unsolved mystery at this point.

Kitchen shears-bottle opener-canning jar ring crimper/opener--Just a WAG!

[Chillylulu]

Here's my wag - those look like they would fit several types of small shut-off valves.  Doesn't explain the scissors though....,

Snips for cutting off "Lock out-Tag out" tags?

Snips for cutting off "Lock out-Tag out" tags?

I like it!

[Lewill2]

Lockout tag out tags should be put in place with locks so only the person working on the equipment is able to remove it with their key. You shouldn't use wire ties or other devices.

Trailer security seals maybe but these pliers don't look heavy duty enough to cut the metal ones, maybe the plastic ones.

My 2 cents 

[blackoak]

I tried to use it to open one of my favorite beverages and although it will open a Miller Lite beer bottle, it was hard to use it that way. The prongs are spaced to far apart to get leverage to pry the cap off.

I don't think those snips would work on any lockout scissors or padlocks that we use up here in Northern British Columbia. I ran a construction company for many years and had  to cut locks off a time or two and we usually used a big bolt cutters or a zip cut. Generally happened when an employee went home and forgot to take his lock off, our procedure was we had to contact the person by phone or whatever before cutting the lock or scissors. Proved very costly in some cases, but you had to make sure the person was not on the job site. I think chilly maybe be onto some thing with his take on it. When the you close them up does the clamp closest to the jaws form a ribbed concentric circle on the inner and a hex on the outer ? How long is this guy overall and how long are the jaws of the snips?

rereading Chilly's reply, if it was for valves, the scissors could be use to cut off any
out of order tags.

these could have been used before OSHA's mandates.

just a thought.

[Papaw]

Holding out for lockout tags-   

[turnnut]

good find Papaw,

and string was also used. easy cut.

[Papaw]

Still don't know if the other part will turn valves or such.

[geneg]

Hard to tell without a scale for size reference, but the serrated opening could be for the stem of a boiler drain or valve, the other opening for a specific jamb nut on the same, & the cutters for the graphite impregnated cord that was used for packing material.
