I am clumsy. I also like straight-up martinis. Problem is, the more martinis I have, the clumsier I get. So I order them in a rocks glass because I don't want the busboy to have to scurry over there with the long-handled dustpan to sweep up my shards since the shape of a martini glass seems designed for me to mishandle and break.
As one of my product design professors always used to say, "You shouldn't have to adjust to your booze vessel; your booze vessel should adjust to you." (Although he may have used the word "product design" instead of "booze vessel.")
NYC-based design firm AMT Studio, run by French-American-Dutch Eindhoven grad Alissia Melka-Teichroew, has the answer to my problems. Their InsideOut glassware collection comes in smooth, grab-friendly shapes, while the inside retains the classic shapes of champagne-, martini-, liqueur- and shot-glasses.
As for that last one, I've never had a problem handling a shot-glass, I typically have a problem handling the tequila my friend enjoys ordering inside of them. One request, Melka-Teichroew: Please swap out the shot-glass for a snifter!
Anyways, as an added bonus, the double walls provide a measure of insulation, keeping your drink cool just a bit longer.
