Try to find some old Gerbers from the 1960's-70's with the tool steel blades.
Years ago, maybe 15 or so. Gerber made the Gator with a drop point in 154cm, IIRC. I liked it, but lost it....
I believe that I have one, still in the blister pack. Brother gave it to me for Christmas, many years back.
For the OP question, D.H. Russell Bird n Trout or KOA Cub.
