Most modern ice cream scoops just don't live up to their claims. Ergonomic, teflon coated, anti-freeze filled—there is no shortage of ways to re-invent the wheel. I picked up my ice cream scoop at an antique store in Santa Cruz, California. They had some truly antique looking ones that looked to be a hundred years old, but the plastic handled model I picked up was reminiscent of 1950's era engineering—thick metal and plenty of chrome. It is the kind of ice cream scoop I remember the ice cream stores had when I was a kid, complete with a thumb lever that magically separated the ice cream from the scoop with a rotating blade.
Fortunately, you don't need to go the antique store to get a scoop like this—Hamilton Beach still makes the Disher ice cream scoop.
