Cheap Shot Glasses
The Whiskey glass that Deckard uses is called the "Cibi" glass as designed by Cini Boeri for Arnolfo di Cambio in 1972. And yes, this classic crystal is still for sale. You can get the "Double Old Fashioned" glass that Deckard uses from Phil Steinschneider, who sells the genuine Arnolfo di Cambio lead crystal glasses. Or you can try Tuscan Hills (who charge a little more when you include shipping costs), but offer a range of four different sized glasses.
