Yeah, growing up my mom had a grapefruit knife. It's used to "scoop" the flesh out of half z grapefruit. It's a really weird looking utensil if you don't know what it's for. Interestingly I can't find any pictures of what we had online. Ours had a serated blade (both top and bottom) and was arc'd through 90 degrees to the side.
