Sentou Mesu (戦闘メス, Combat Scalpel
A Large Five Foot Ten Inch Steel Scalpel. Scalpel Head is One Foot long.
While scalpels are used for medical purposes, this large version is used for combat instead. While it seems simple because of it's design, it's perfect for being used for Chakra Enhanced Strength for it's strikes on the blade or on any metal part of this specially designed spear for a Medical-Nin. The blade of the spear is extremely sharp and one touch will instantly cause a small cut on someone. When used in battle, muscles are it's normal targets as it's user will attempt to remove the muscles or cut the tendons from it's target.
There is a small mechanism within the spear for one to insert their poisons in either a liquid or solid form to be inserted into the target at the tip. It travels from the base of the spear to the tip, until it is struck inside of someone where the user can press down where the mechanism is located and makes the substance release from the tip.
Due to being steel, it's an easy conductor of Lightning-based Chakra Flow and Lightning-based techniques in the form of Ninjutsu and Ijutsu.
Sutorimu Hisan (ストリーム悲惨, Steam Misery
A Double-Ended Spear with forked blades that intertwine with each other, colors of dark red, gold, and black that compliment each other. It is quite large for it's size, yet the inside is hollow. The blades of the spear are each 10 Inches Long while the base is 4 Feet, a chain in the hollow parts connecting it together tightly.
The spear is specially made in order to contain Steam from the special Boil Release of Kokuo, the steel being able to reach extremely high temperatures. Touching the spear will cause second degree burns when the user uses a Boil Release Chakra Flow, along with heating up weapons that it comes into contact with. It's spear heads are made to stab into and be twisted into the enemies in order to trap itself inside of it's target and pull out muscles or internally heat up the enemy. It is made ideal for the Kokuo's Jinchuriki in mind, as the hollow insides cause the spear to be lighter to carry while still remaining fully made of steel except.
It serves as a great conductor for Kokuo's Boil Release Chakra Flow, as the body and blades can make use of the heat that it produces. It directly release steam into the body of someone stabbed the small holes that are placed along the blades, visibly showing steam coming from the weapon as it has built up inside.
