Ever since Bar Agricole opened in San Francisco, we've found ourselves thinking about cocktail shakers. Here are two current favorites, one high, one low (in price, at least).

Above: Designed in 1957, the Avio Cocktail Shaker from Alessi is a modern classic; $117 at Canoe.

Above: Schott Zwiesel Schumann Stainless Steel Cocktail Shaker; $39.95 at Sur La Table.
