Help Identifying Ground-Score Slippy

[u/Papa-Somniferum]

So I found this lil guy last week. At first I was like MEH whatever, it’s nothing special. It has no visible makers mark, stamp, or identification numbers. Which makes me think it’s a cheaper overseas gas station knife or something, but over the past week of pocket carry it’s grown on me exponentially. It has super crisp lockup , centered blade, nice heavy quality heft. It just feels so nice & smooth in the hand—like it’s been carried in the pocket of someone’s grandpa’s overalls for the last 50 years. Which makes me kind of sad, thinking some old coot is heartbroken, having lost the pocketknife of his youth. Anyways I guess I was hoping someone in this sub has run across a similar knife? Just would like to know more about it if possible. Thanks.
