K's arsenal

Name: K’s prosthetic metal hands
Appearance: a pair of well crafted metallic hands almost resembling a “puppet” like structure with more developed, human like features and joints, these hands fix to the wrists. The wrists of these contain very large spools of wire with in the casings and affix to the arm by a series of straps.
Special Abilities: Using raiton chakra the user is able to move and feel touch with these hands as if they were totally real. In addition to being acceptingly damage resistant the metal is very receptive to the users chakra and naturally enforced by it, the fingers have been modified to thread the wire from the spools out though the finger tips for movement and justu reasons
Rank: A
Origin: Created for K after the tragic loss of his hands by cloud village medical ninja, though he could no longer make music as he once did the metal fingertips produced a new sound against his instrument’s strings and gave birth to a new kind of sound.

Name: Wires, Brass Wires and Razor wires
Special Abilities: The wire is very receptive to the users chakra as a natural conductor working emptily well with raiton chakra and jutsus, the razor wire can cut much more easily and is quite simply more weaponized, the brass wire serves a special purpose as brass is one of the few metals that makes a good conductor with out being magnetic allowing the users to effectively stand up against users of magnetic jutsu while still using their primary weapon.
Rank: E
Origin: Wires have always been a common tool for ninja, usually used to fix tags to kunai or as an element in traps, some ninja learn to incorporate wires in to some jutsu and it was for these ninja that brass and razor wires were made.

Name: Thundercloud smoke bombs
Appearance: Smaller light blue balls with yellow rings down the center and red dots on either side.
Special Abilities: Like an ordinary smoke bomb this tool explodes in to a dense fog like smokescreen obscuring visibility, however these particular smoke bombs have been formulated to generate a mist which is highly conductive and receptive to electricity, as if a storm cloud had been called from the sky down to the battlefield making lightning jutsu much more effective.
Rank: C
Origin: Invented by cloud ninja who had become frustrated with raiton’s need for a conductor to pass through in order to create an effective tool and trap for opponents

Name: Weighted offensive leg armor
Appearance: Typically wrapped in bandages these bulky looking devices include heavy metallic boots with a rounded shape and treads under the shoes for extra traction, an oversized armored shin guard and a pair of heavy steel kneepads, these are acceptingly heavy and contain a variety of hidden mechanisms which can be released with simple elementary chakra control
Special Abilities: A disadvantage to these armored pieces is that they weigh over four hundred pounds, but their weight is compensated for in durability being able to simply “kick away” attacks with greater force and block metal weapons easily. In addition to their added weight and durability the armor has a verity of useful hidden features, the soles of the feet can deploy a series of metal spikes to increase traction and damage, the toes possess retractable blades to add cutting to kicks, the shin guards deploy similar spikes and the knee plates possess identical hidden blades.
Rank: C
Origin: Weights on ones legs are not a novel concept in taijutsu but eventually the notion that weighted armored plaiting could be used in place of simplistic weighted wrappings allowing them to act as more than just a handicap leading to this current all metal design.

Name: Lightning rod kunai
Appearance: At fist glance these kunai are only abnormal in their yellow handle wrappings and cubic back ends as posed to rings but in reality these are a complex pre-prepared weapon loaded with a very small seal and raiton chakra.
Special Abilities: After these kunai hit something the back ends actually open discharge a few sparks of electricity, this is not to attack but rather to direct any stray currents of lightning to the kunai and by extension the target near by
Origin: Often times Lightning can not be redirected once called out by a raiton user, and some lightning techniques are particularly hard to aim at smaller targets, for this purpose the lightning rod kunai was made allowing raiton users a newfound level of flexibility in combat.

Name: Shamisen
Appearance: a very common and totally ordinary traditional japanease three string interment with a round base and triangular head, this could be used for sound jutsu but it has not been reinforced enough for any real practical use
Special Abilities: None, it’s a normal Shamisen
Rank: E
Origin: A common string instrument preferred for its portability and (ordinarily) traditional sound, though K plays it quite differently with his metallic hands

Name: Kinkaku Force Life saving chest seal
Appearance: The emblem for the Kinkaku Force over the heart in black
Special abilities: the seal is not a curse seal or a summoning tattoo but rather a very simple fuuninjutsu (seal technique) that administers a shock to the heart if it stops beating to restart it just once, allowing the ninja to go on living if they are taken out in battle, a revived user can not fight right away but will be able to survive afterward if they are not poisoned or damaged to severally and still possess enough blood in their system, if given enough recovery time they may actually be able to resume fighting, one use only
Rank: A
Origin: Created by the elite cloud village squad to allow their members to identify each other later adapted in to a very formidable seal that gave the Kinkaku Force the reputation of being nearly invincible

Name: Summons Tattoo
Appearance: A black spiral around the right shoulder with a symbol of an eels head over the wrist with an x on its forehead falling just before the elbow
Special abilities: Rather than a scroll this tattoo constitutes the summoning contact, forearm on how the user places blood on the tattoo different eels are summoned
Rank: D
Origin: Given to K by queen Umi of the stromy seas the leader of the eel clan

Name: Solder pills
Appearance: Small black pills
Special Abilities: increased stamina and chakra flow
Rank: D
Origin: One of the more common pills. A soldier pill is said to allow a ninja to battle for three days and three nights straight. Though in truth their effects are not as significant, their ability to restore a users stamina still make them an extremely useful item on the battlefield. While this does allow the user to gain a short stamina boost, it cannot go beyond human limits. Taking two soldier pills within an hour of each other is dangerous, and taking a third may cause death.

Name: Lightning gems
Appearance: Two round dome like yellow gems in the palm of K's metal hands
Special abilities: The gems are placed in the center of a seal inscribed on the inside of the metal palms, these gems act as a means of absorbing and storing massive amounts of lightning, these can be made to "charge" and take in the users chakra or lightning from another source over time or all at once from another source and released in a variety of ways for near jutsu like attacks, K uses this for various jutsu that require larger amounts of lightning as well as in his lightning absorption technique and for a few other lightning techniques such as concentrated beams, blasts or orbs of condensed lightning
Rank: B
Origin: an adaptation that K invented for his metal hands to fundamentally increases his reserves of lightning and compensate for the taxing effect lightning jutsu can have on chakra

Name: Hiraishin no ken (literally “Lightning rod sword”)
Appearance: Appears as a very dark, duller tanto, a defensive sword at a blade length of under one foot with a longer guard and a complex handle with cross hatches carved in to it, the side of the blade has a silvery lightning bolt carved down it with a round dome like yellow gem in the pummel.
Special abilities: The Hiraishin no ken is a very specialized form of steel with an ultra dense, super conductive material infused in to it that, once charged with raiton chakra causes the blade to become, quite literally a super powered lightning rod, absorbing all near by electric fields in to it, the lightning gem in it’s pummel allows it to absorb and store up large amounts of electricity for later use
Rank: B
Origin: Crafted by master sword smiths of the cloud village with the aid of a ninja using the steel release, part of a two sword set as the defensive blade that gathers lightning for its brother

Name: Kaizen Chō Biburāto Raitontō (literally “Improved super vibrating lightning release sword”)
Appearance: The tanto appears as being quite bright in shade and is unique in many ways, unlike most tanto it is double sided and strait with no noticeable bloodline and is also devoid of any sort of guard of hilt, the pummel is a simple, brass cap. What sets this apart from other Cho biburato raitontos is the three brass rings embedded in the base of the blade.
Special abilities: The super vibrating lightning release sword is a common specialized weapon in the cloud village, tantos made to channel raiton chakra in to them and vibrate at ultrasonic speeds to possess a cutting power beyond most wind techniques, the improvement on this design mentioned in the name is that the actual heat from the vibrations is increased quite a bit with out damaging the blade due to the rings and a reinforced design, the vibrations are also directed down the edges in a cycle as opposed to simply resonating around the edge, increasing the cutting power further once enough lightning has been fed in to the blade. Even able to discharge lightning from the vibrating edge to increase the range and cutting efficacy of the weapon
Rank: B
Origin: Crafted by master sword smiths of the cloud village with the aid of a ninja using the steel release, part of a two sword set as the defensive blade that draws lightning from its brother to use in attacks
