Cool avatar bro.

suppose we're doing a drill related technique of some kind. Eeyyyup.
Wan picks up his blood stained blade of grass and concentrates on gathering chakra and channeling it into the blade. He dashes towards a member of the aburame clan and uses his chakra to exaggerate the power of the blade. Wan then makes an upwards slice, cutting off one of the bug person's arms. The cut is so extreme that the person is sent flying up into the air by the cutting and piercing power of Wan's deadly blade. Of grass. **** yeah. After that, Wan jumps into the air, placing himself above the bug master and... makes drilling slash. It impells them to ground.
My thoughts and insight are that I should have applied for mod on the basis of improving the canon jutsu descriptions. Other than that it's an okay jutsu.
With vorpal blade of grass in hand, Wan chakra bends his chakra by using his mind and body to gather it and channel it into his blade. He then makes a slice through the air while releasing the chakra from the blade and manipulating it to create a blade of chakra to fly forward at a tree. The arc of energy appears red due to being used with his blood soaked blade, of grass.
Just learned the airbending slice equivalent. Also know samurai techniques already. I'd use this to... slice a bug in half.
Wan sets his trusty blade of grass down for a moment when suddenly a katana drops from the air, stabbing his blade and cutting it in half. As this is an incredible feat, Wan takes this new sword and names it grass cutting sword. He stabs the new sword into the ground and performers a few hand seals and concentrates on gathering chakra and channeling it into his hand. At the same time he molds his chakra to be sharp and... and energetic to create raiton chakra. He then grabs his grass cutting sword and channels the ration chakra into it and shaping it into lighting to surround the blade. He then uses the sword to cut grasses in half.
I'd use it to cut grass because it has the elemental advantage.
