The Original Zeroll, $16
Zeroll's aluminum scooper, a stalwart that's been around since 1935, earned a thumbs-up for its effortless rolling motion, which yielded nearly flawless spheres every time. The thick handle is filled with a defrosting fluid that warms on contact with a bare hand, in turn heating the scoop. This, combined with the extra-deep bowl's beveled edge, makes carving into a carton a cinch. Hand wash.
