No ordinary waiter's friend, it is a completely 'idiot proof' non-slip corkscrew.  It is special because it:

• incorporates its own foil cutter
• is light
• is easy to carry
• is easy to use
• is designed so that it's 'pirouette' action  prevents the lever from slipping off the rim of the bottle and cutting into your hand

Once you have used this, you wil never want to use anything else again - promise!
