Well, the Juice series is Leatherman's attempt to compete directly with the ubiquitous Swiss Army Knife. They're aimed at the young, affluent, urban crowd who ski, backpack, etc. SAKs have corkscrews, mostly, and a certain segment of the market likes that very much.

This segment of the market is likely to bring both beer and wine on an outing, so a corkscrew is highly necessary. At condo-type ski lodges, in mixed and intriguing company, the corkscrew on my SAK has saved the day more than once.

Europeans, of course, go for wine as much as beer. Even the surplus W.German military pocketknives I've picked up have a corkscrew as standard equipment. So if you want to break into that market, offer a corkscrew.

The only use I've found for a corkscrew in the bush is to loosen stubborn knots in shoelaces and paracord. It slips in without damaging the rope, you twist it a couple of times, and give it a pull. Works like a charm.
