Stick
You throw the stick. Mettaton catches it in his mouth and winks.
Text upon using the stick during Mettaton EX's fight
The Stick (JP: ぼうきれ) is the weapon equipped to the protagonist at the beginning of Undertale. Its defensive counterpart is the Bandage. It provides no statistical improvement.
Once unequipped, it cannot be re-equipped, but it can be used against certain monsters in encounters with differing results.
When attacking a monster with the Stick, a single bar slides across the attack meter from the left. When confirming the attack, the animation depicts a curled, red slash animation. This animation and sound effect is shared with the Toy Knife, Worn Dagger, and Real Knife.
The Stick's attacking animation
Using the Stick causes the protagonist to throw it, then pick it back up. This does not cause the Stick to be consumed, and, in most cases, has no further effect. However, using the Stick in certain battles can affect their outcome.
- Using the Stick against any dog enemy (including Endogeny) immediately makes them spareable.
- If used against Papyrus, he fetches it.
- Using it against Madjick makes it think of the protagonist as a fellow wizard, making it spareable.
- The first time using it during Mettaton EX's fight rewards 700 rating points.
- If used during the final stage of the fight, when he has been reduced to just his head and torso, the reward is 1400 rating points instead.
- If used any more times, it only gives 1 rating point.
- Comments in the code of the Undertale Demo imply that the Stick was originally called the "Butterknife".
