Curious About Knife

[sheepherder]

I was reading an amusing thread at Still's forum about a dual-magazine pouch offered by revshop and I browsed thru Ken's listings to see what else he had...To my surprise, he has two knives listed of which I have a similar knife sitting in front of me...

I've had mine for about 19 years, kept unrestored [?] because I like the patina on the blade...I forget where I got it; online maybe, or a local gun show...

Anyway, Ken's are marked 'Cattaraugus 2250' while mine has no markings on the knife or the sheath...

I posted pics of it on Bladeforums.com about 10-15 years ago; IIRC the consensus was that it is a Navy storeskeeper's [supply] knife, used to open crates or to start the opening by making a crack that a prybar could be inserted in...

6 inch blade; stacked leather disks; some kind of epoxy at each end of disks; triple steel-disk pommel. Two pins/nails [?] in pommel; left-hand sheath.

Anyone here have any knowledge or ideas of exactly what it was??? May not even be military issue...
