Basic procedure: Get a pouch and get any 2 tools from the same family. It can be 2 Fire Rods, a Boomerang and a Fire Boomerang, a Bomb and Remote Bomb... anything. Use one, swap to the other, and try to use the other while the first's projectile is on screen. It won't function.
The only exception to this is the Tornado Rod, as instead it deletes any current fireball or tornado on screen before placing a new one. This is probably because the Tornado Rod works like that in general, letting you delete old tornadoes to make new ones. Of course, this does mean that you can't have 2 tornadoes out at once, which defeats the whole purpose of having double Tornado Rod.
I'm hoping this isn't intended behavior - there's a lot of puzzle potential with doubling up on tools. Double Fire Rod to have 2 fireballs at once, double Remote Bomb for complex switch puzzles, etc.
