Kama Kama no Mi

The Kama Kama no Mi is a Devil Fruit that gives the user two-inch long claws and the ability to attack with blades of air. Kama means "sickle." It can also come from the word kama-itachi, which means "wind-scythe", but can also mean "sickle-weasel", a Japanese demon with sickle-like appendages, slashing like the wind, referenced to this fruit's powers. In the FUNimation dub, it is called the Sickle-Sickle Fruit. It was eaten by Erik the Whirlwind.

Strengths and Weaknesses
The main strength of this fruit is that it lengthens the nails of the user of two inches, which are capable of slicing through the air itself, creating razor-sharp vacuum blades that can slice through the targets from a distance, thus allowing long range attacks. It is unknown if these nails themselves can be used in close-quarters combat.

This fruit doesn't seem to have any specific weaknesses, aside from the standard Devil Fruit weaknesses. However, the name of the Devil Fruit sounds close to "okama", thus may cause confusion to others in regards to that aspect.

Usage
This Devil Fruit gives Erik power similar to CP9's Rankyaku technique, as Erik is a filler character, and it is unknown which is stronger. Erik's abilities comes from a Devil Fruit power, but the Rokushiki moves are derived from Super-Human Strength. Luffy was able to withstand Erik's attack with ease, while he recoiled after being hit with Rankyaku.

Techniques

 * Kama Kama no Tsumujikaze (カマカマの旋風 Sickle Sickle Whirlwind): Erik releases a powerful air blade that slashes the enemy multiple times on contact. It is strong enough to slice through rock ground. He also launched two of then in a "X" formation. In the FUNimation dub, this is called Sickle-Sickle Whirlwind.


 * Kama Kama no Kamaitachi Midareuchi (カマカマの鎌鼬乱れ撃ち Sickle Sickle Wind-Scythe Chaos-Attack): Erik's "ultimate kamaitachi technique". He slashes many times, releasing multiple air blade sickles on to the enemy before unleashing a powerful whirlwind of razor air that can slice through rocks. In the FUNimation dub, this is called Sickle-Sickle Wind Slash: Rapid Fire.

Trivia

 * Due to a mishearing of the Devil Fruit's name, some of the Straw Hats mistook the name of the fruit as "Okama Okama" and thought Erik was gay. In the FUNimation dub, this joke is carried over with the Straw Hats mistaking the Sickle-Sickle Fruit for the Sicko-Sicko Fruit.
