You misunderstand. Not kitchen items. Drills are one of battle technology weapons. That and other "Actual" varieties Eggman would use would stem from his back attachment device.
Eggman has NEVER used a "back attachment device" in any of his game appearances, not even once. So you think you're able to suggest any sort of ridiculous idea just because it's non-canon and you think that anything goes. It doesn't work like that.
