Deku Stick

Deku Sticks are items from Ocarina of Time and Majora's Mask.

Deku Sticks are the harvested stalks of Deku Babas. Though most famously used as a makeshift torch, Deku Sticks are to a child what the Giant's Knife is to an adult (seeing as how they break). Deku Sticks deal twice as much damage as the Kokiri Sword.

The infinite Deku Stick glitch
In Ocarina of Time, it is possible to make a Deku stick not break after its use. To do this you had to take out the Deku stick and perform a Jump Attack at the wall at a slight angle. If done correctly the Deku stick should hit the wall twice and the top half will break off. However, Link will still be carrying the broken portion. The broken portion of the stick can be used normally but will not break. Another method is to enter Jabu Jabu's Belly, and get electrocuted by anything while holding a Deku Stick. The top part of the stick will break off, but the bottom will stay. Notes: the broken Deku stick can not be used to light torches and will turn back in to a regular Deku stick if put away, performing this glitch consumes one Deku stick. If done with only 1 Deku stick remaining, then you won't be able to swing it, but you can still perform a Jump Attack.

This glitch is also present in Majora's Mask, although, it is not as easy to achieve. It can be done by taking out a Deku Stick, then performing a Jump Attack against a Dodongo.
