Once upon a time, flasks were used by Don Draper-esque gentlemen. Stylish bastards needing a nip of something to get through a train ride home from the city to the suburbs. They'd fill up these silver, engraved showpieces with whiskey or scotch and slip them into the inside pockets of their suit jackets.
But somehow, the profile of the type of people who carry flasks has been significantly downgraded. Namely, the people who carry flasks are underage teenagers. They buy cheap flasks with ridiculous sayings on them from somewhere like Spencer's (it still exists, America!) so they can sneak booze into one of those sketchy "18 to party, 21 to drink" clubs, order a cranberry juice, and go into the bathroom and pour in vodka from their flask. A less-than-glamorous use, that's for sure.
Let's elevate the flask back to it's golden days, shall we? This Stay Sharp Flask ($148, Best Made Co.) is larger-than-normal (8 ounces), made of pewter, and engraved with a phrase your grandfather would approve of—"stay sharp."
