I can play. This was my Grandfather's. He used to use it to shoot cats on construction sites in NY city back in the 20's or maybe 30's. The story he told was he would shoot nails out of it.
I have visited this site before and didnt see the intro section before so allow me to rectify this error. I collect knives and right now I am mostly focusing on slip-joints but I spread it around. I have had a knife in my pocket since I was eight but I still wish I was better at sharpening...
