Remember those stainless knives with blade, screwdriver, punch and can opener surplused out several years ago? They were stamped U.S or branches of service with "checked" handles. I have a knife identical to these with exceptions.
1) carbon steel blades
2) brass scales
3) Has screwdriver opening assist pin
Blades are dark and pitted indicating age. It does not appear to be foriegn made copy. It had a shackle at one time, now gone.
There are no markings anywhere that I can find. Can anyone help me identify?
Thanks, Bob

This could be an early model (circa 1945) possibly made by Kingston.

I'm new to this forum, but have been on a few others online for a few years and just ran into this site recently.I'm into knives of all sorts,but my deepest interest has always been military knives.I'm far from an expert on anything,but I may be able to help you out on this.Your knife definitely sounds like a WW2 pocket knife.The style eventually evolved into the all stainless MIL-K-818 knife of which revisions are still being produced.It was probably marked at one time,but it was on the bail which you said is missing.Kingston and Stevenson both marked their knives on the bail.The pin on the bottle opener/screwdriver blade has long been a topic of speculation.Many believe it was intended to serve as a drift punch of sorts to remove pins on firearms for field stripping.I tend to lean that way as it seems the size of the pin has changed over the years as the service rifles have changed.
