Big Heavy Grey Flipper Knife. Drop Point Serrated not A Medford Or Kershaw Or Zt For Sale

This is one of a set of knives that I got. They are unbranded and I don’t know anything about them expect that they are sharp, large, heavy, and appear and feel high quality. All solid stainless steel design with window punch, half serrated blade, liner lock, and thumb studs with flipper. I may keep one for myself but for now both are for sale. I have see. Them used as watch knifes and elf monkey. Not sure who really makes them but they seem to be widely customized with other brands like the NRA
