neil.rSame here. I rarely find myself in a bind that a corkscrew would get me out of. To be fair, I'm not a big wine drinker and I don't carry a bottle around randomly in case the urge strikes.
CoastalI've never used the corkscrew on my multi tool for opening wine bottles, on the other hand I've used it to undo knots, go through leather, undo stitches (last night I removed an annoying detail on a clothing article) and such on numerous occasions. Basically, I mainly use it as a needle (instead of the tip of the knife) with an amazing grip :)
crimsontongueNope. Doesn't fit. I have this knife and thought the same thing, that the SAK cork-driver would fit, but the Boker corkscrew is different enough so it won't match up.
