Doriru Doriru No Mi (Drill Drill Fruit)

Not sure if it's already made but if it is please direct me to it.

Name: Doriru Doriru No Mi (Drill Drill Fruit)

Capabilities: Allows the user to morph his body-parts into drills however if the drill gets harmed so does the body part he used. For example say that he turned his left arm into a drill then that means if the drill gets harmed so does his left arm. Also he can only turn up to 2 body parts into drills. It would take at least 5x the strength of a hammer for the drill to either be dented or broken. The wielder of this fruit has to be skilled with swords or at least of some experience on using swords. These drills cannot kill someone by one hit but can harm him, it will take at least 1-2 hits to kill a normal human/citizen.

Type: Paramecia
