I actually know why the SAK has a cork screw, its kinda funny, but when canning first was the invented they used bottles. So when the inventor of the SAK made his knife, he added a corkscrew.T he can opener was later invented and added, and the corkscrew was never removed from the design. Yes I know a bit of pointless trivia.

I can draw any knife I want, I just can't afford to make it, or buy it.....
