diamalloy kc-18 made in USA
gotta be useful for something

Hose spring clamp pliers, the odd looking cuts in the jaws allow the opposing sides of the spring clamp to be squeezed together to allow removal of the clamp.
Very handy to have when needed, flat jaw pliers don't hold well under pressure!

I have a pair of those in the tool box. Handy for the spring clamps on old cars and washing machines.

Here is a similarly purposed Craftsman version. The groove configuration appears to be a little different. I don't think I have see a Craftsman tool with so many factory markings on it. It has "Craftsman 4732 USA", there is also a small LC just to the left of the part number. Those are stamped. You can see most of the "JKB" that is also stamped into the one leg near the jaw, and just below that, you can barely make it out in the picture but forged into the handle is a very tiny, vertically printed "Y 3 1", which also appears in the same spot on the other leg. That's a lot of markings. I wonder if the "JKB" is a factory or owner mark?
On second look, it appears the groove configuration is pretty much exactly the same.

Hose spring clamp pliers...
Yep; I believe they are called Corbin clamps...
-
...there is also a small LC just to the left of the part number.
"Lectrolite Corporation"

You can use the pliers straight on, or sideways in restricted areas. Nice to have a set of pliers like this for those kinds of Corbin clamps.

any guess on the "JKB" marking? or the "Y 3 1" forge? You can barely make those out.

I believe Y.3.1 is a date code, like on Danielson pliers.

If 'Y 6 1' is a danielson style date code it would have to be 1961.
There is a close , interesting sequence of events here. The first usable spring wire clamps are probably after 1954 when Golden's patent fixed the fact that clamps formed as a circle were not in fact circular when streched around the hose. That patent went to Eaton Mfg.
The earliest pliers I find are shown in a 1957 patent, that fixes yet another 'circle is not round' issue. (2793414)
The Corbin trademark was not registered until 1964, but probably was in use a little before then (reg to Emhart Industries, who also held some patents for spring clamps)
Now, the interesting thing is, Lectrolite Corp goes away in 1962, because SK bought them, so if 'LC' is in fact them, the pliers were made for a very brief time, and by a third party as contract to a company selling them as contract...a very odd thing to do...
The craftsman catalog for 1960 does show hose clamp pliers, tho as the Dunlap brand..
As a stray oddity, the first spring wire clamp goes back 60 years before, to 1900 (647693), it likely worked, but had no ears, so there was no way to get it off afterwards, and it probably wasn't all that much fun to install either..(The ears came in 1935 when a fellow adapted it to hold the nipple on a baby bottle)

If I remember correctly my 60's era Chevy's had flat spring hose clamps that could be removed and installed with a regular set of pliers.
I have a set like the ones kxxr posted that are marked "JAPAN" inside each handle and also marked "Drop Forged" adjacent to the pivot on one side.

I recall those flat spring clamps. I thought the round ones were older though as I recall working on mid 50's GM vehicles with the round spring clamps. But maybe they were not OEM - the cars were far from new when I worked on them.
