My father carried either a Buck 110 or something like it in his back pocket. As a kid in the 1980's at a the local county fair I picked up a "made in Pakistan" knock off that didnt last very long.
In the 1990's i went to buy one but bought the Browning knockoff instead, as it was lighter and less expensive.
I have a Buck 110 that was purchased new and given to me by a friend (Spartan) just a few years ago, a 2017. The quality was such that I really appreciated it, and went looking for more. I found a green Ecolite Paperstone (micarta?, resin?) version in an old hardware store dating to 2011, NOS. Was gifted another with the LT handles. These blades were all just RAZOR sharp.
Finally I found a used one on CL that I have tentatively dated to around 1978. I got it, an old Western, and an OG Buck 192 (different metal than today) from the same source. Anyway, now I have a very detailed map that will allow me to either confirm that, or definitively date it to some other year, presumably not far off from 78.
Thanks VIC
