I can honetsly admit that, if one function on my Vic Spartan (my EDC) annoyed me as useless, it was the corkscrew. I have never used it, and figured I never would. It basically held my lanyard ring in place. Anyhow, when I got my Svord Peasant, it was in it's sheath pretty good and I figured out that the corkscrew would make a good tool to remove it and help break in the new sheath.
