I vote for the corkscrew too. My SAK proved it's usefullness at a dinner party some time ago when the hosts couldn't find their corkscrew. Actually it works better than many corkscrews I've used.
Of course some vintners are switching to screw tops. Reminds me of Chateau Boone's Farm, 1972. <img src="images/graemlins/grin.gif" alt="" />
