Why this bottle opener earns its place
The waiter's friend is the pattern every other wine tool gets measured against: a worm, a small blade and a lever that all fold flat into something a member of staff can carry in an apron pocket for a whole shift and still have on them at the end of it. The pull-tap version is the upgrade worth having. Its lever has two steps rather than one, so it bites the bottle lip low, lifts the cork halfway, then re-seats higher and takes the rest. That second stage is what gets a long cork out in front of a guest without a strained wrist or a cork snapping at the shoulder.
Behind a bar it earns its keep twice over, because the same folding body carries the cap lever for bottled beer and mixers. That is the reason this pattern tends to be the tool a venue buys in quantity rather than one at a time — it covers both jobs, it costs nothing in drawer space, and staff can keep it on them instead of hunting for it.
Silver stainless steel is what makes it last. It goes in and out of a pocket, gets wet, gets wiped, and comes back looking the same, and metal keeps the folding action tight over months of use, which is really what decides how long a corkscrew stays pleasant to work with.
