Normal SizeLarge FormName of weapon: Decapitating Katana
Who owns the weapon: Sachi Irezumi
Where it was found/Who made it: She bought it off of a traveling merchant, at the time she had no idea of the swords ability.
The Range of the weapon: Range of basic katana, Large form = 8 feet, 1 foot wide, 4 inches thick (not at end where blade is ).
Weakness: Normal katana in normal form (has all weaknesses of a basic katana) Large for is much heavier making it just about impossible to use with out Zanbatō style training.
Description: This katana took a total of 30 years to craft due to the simple yet amazing ability it has. Once it was completed it was put away in a large castle and forgotten about years later until one day a group of ninja raided the castle and took the katana. The katana was then sold over and over across the lands to many traders till Sachi came across it. The katana when in its normal form is nothing special but when a certain amount of chakra is focused into the blade it grows quiet bigger in size. By focusing half of the amount of chakra the blade is able to change back to its normal form.
There is no limit to how long it can be in ether form. Due to the larger form being so large, Sachi wont be carrying it around like that all the time.
Abilities:*) 4 chakra points to make the sword grow bigger.
*) 2 chakra points to change it to normal.*) A Genin level,the sword takes 1 post to begin transformation but does not take away from using a jutsu that post. During those posts the user can not attack but may block a strike if the blade is in front of the attack. Upon full transformation of the blade,four chakra points will be deducted.
*) Once chuunin rank or higher,the sword is able to transform and be used for a attack on any post of the transformation. Chakra cost is the same as during Genin level. Meaning it will be deducted once the blade reaches full potential.
The sword gains 2 feet long, 3 inches wide, 1 inch thick per post of transformation. Meaning it is 2 feet long, 3 inches wide, 1 inch thick on the first post, 4 feet long, 6inches wide, 2 inches thick the second... and so on.
Special Note: Requires 4 posts in between transforming of blade blade. Additionally: There is a small dagger with a 6 inch blade that is made to look like the end of the sheath. The Sheath when having this dagger in it makes the katana appear longer then it really is and also the dagger comes in handy when you opponent believe you have no more weapons. The daggers handle is perfectly made to look the end of the sheath that only people who can see through objects or people who have seen the dagger know its there.
