TL;DR: Excellent drills, solid material, nice box, all correct measurements. Don't try to eat these drills. That would be a very bad decision. If you attempt an amateur lobotomy, please report it to local authorities. You don't need a drill of this quality either. A cheaper drill will do the trick too. They are extremely ineffective as chopsticks, being too short and too sharp. When placed in a small caliber cartridge (20+ caliber) and viewed with a high-speed video camera, they actually spin in the air, but have no accuracy. Besides, it's a terrible idea. Please don't do this.
