When we're faced with a fresh, blushing half grapefruit, the double-sided Norpro Squirtless Grapefruit Knife ($7; amazon.com) is the first tool we reach for. The twin serrated blade at one end slices on either side of the tough membrane, separating it from each segment of flesh. The curved, toothed prong at the other end reaches beneath the segments, cutting and lifting them free of the pith. When it's time to eat, the Trudeau Grapefruit Spoon ($13 for a five-piece set; amazon.com) has a tapered serrated edge that dislodges and scoops up each bite. It's ideal for scraping up bits of fruit the knife might have missed, and its bowl, of course, spoons up the juice.
