Similar in concept egg beaters and paint mixers I suppose, but designed specifically for pumpkin gutting. You might be able to use an egg beater or paint mixer attachment to loosen some strings/seeds... but the curved blades on the end of this Pumpkin Gutter are sharp enough to slice their way through quite well. And then the blades can also thin down the inside flesh of the pumpkin which helps a lot.
The edge is like a blade, but not razor sharp, meaning you won't cut yourself if you touch it. WHILE IT'S NOT SPINNING, of course! Please NEVER stick your fingers near the end of the gutter if it's attached to a drill!
Speaking of... I'm looking to pick up a new drill this year. I need something with a little more POWER. Anyone have any recommendations regarding drills? Maybe one you've had good experience with the gutting process (or other power jobs)?
