Above is the aluminum Zeroll scoop, which was created in 1935 and claims to be the original ice cream scooper. The key, according to the company, is a heat-conductive fluid in the handle that warms the ice cream, helps it roll, and eases release. The design has been knocked off plenty (we have a no-name brand that's similar). One possible downside: it can't be put in the dishwasher.
(All of these scoops — and many more — are available at Amazon)
