Japanese “S T MARKS” Knives.

[New_Windsor_NY]

Yesterday afternoon, this fob or key ring, pattern or style of pocket knife, arrived in a group or lot of pocket knives that I bought. It now becomes my first example to be posted under this new topic or thread. I did NOT buy the group or lot of pocket knives just to obtain this particular pocket knife. But, it did get added to my general, "foreign born", pocket knife accumulation. It is a JAPAN, one blade, one tang stamp, 1 1/2” closed (not including the bail), fob or key ring, pattern or style of pocket knife. The main blade front tang stamp says, "S T (over) MARKS (over) JAPAN" The main blade does NOT have a half stop. The main blade does NOT have an opening snap. The main blade does NOT have a closing snap. Overall, this pocket knife is in FAIR condition. This pocket knife did NOT need any cleaning at all. I just wiped it off.
I took some pictures and here it is.
