One Minute Knife Video: Case peanut(?) from the 50s(?). My first and oldest knife

Here we have the Very first knife I owned, rather stole from my Grandfather when I was 5. And some how after many many years and moves, I still have it. Wow. I really do not know much about this one (if you do, please comment) except it predates the XX models and as you can see, has real brass liners. I believe it’s ebony scales. This knife has been sprung and won’t close all the way, the tip reprofiled a number of times as well, but it holds a special place in my heart.
