Because I wanted to think of a transmutation ability that could be used as a tool, as well as a weapon, like bungee gum or Machi's Nen Strings:

Nen Type: Transmutation

Name: Nen Blades

Description: Due to how versatile this ability is, this description may get a bit lengthy.

This isn't that hard to understand I hope. As the name points out, I would transmute my aura to give it the properties of a sharp object, such as a knife. While it may seem like a simple ability, that is where its power lies, in its simplicity. After all, simple Hatsu idea's like Machi's Strings or Franklin's Bullet's are extremely powerful in practice due to their simplicity.

I would be able to make my aura change into blades(concealed with In) anywhere on my body, sharp enough that even master enhancers like Uvo aren't walking away if I put all my weight/strength into a strike, having one on my elbow and wrist, maybe on the back of my neck, or even just have a blade sticking out of everywhere and turning myself into a human porcupine. Maybe I give myself wolverine claws, or the claws from Prototype 2. I could make the blades as long as I wanted to(or as long as physically possible if you'd like), and any shape I want, ranging from a scythe, to a straight knife, to a katana etc.

I would also be able to surround objects with my aura and turn them into blades, allowing me to turn something as simple as a pencil into a lethal weapon, or even take a regular stick off of the ground and turn it into an arrow in less than a second. Most likely I would use this aspect to take something like the hilt of a sword, and use my aura as the blade, giving me a weapon with limitless(but not really due to human limitation) range and forms, as well as something you can't see and don't expect. It would however be possible to use my "sharp aura", to surround and existing blade, to make it sharp again if it was dull before.

Limitations:

 1) As soon as a blade has been broken, I can not transmute another one in that position until I dissipate all other blades made from my aura.

2) When placing my sharp aura around an object to use as a projectile, the blades can only exist is they are moving at a velocity of at least 10 metres per second. While they are in flight they continue to lose strength until my aura completely disappears from the object.

3) While the sharpness of the blade doesn't decrease with it's length, the strength of the blades flatside weakens every time the length is increased. Basically, a blade the size of the earth would break from the flutter of a butterfly's wings, but a 1 metre long blade would survive a train crash(don't take that literally, it's just a metaphor).

4) I can not place a blade directly on another Nen user, but I can attach it to something they might be wearing, such as some sort of clothing.
