Lightning Thrust

One of Daisuki Uchiha's original techniques, Kaminari Tsuki is a jutsu which can act either as a short-range jab, much like Raikiri or can be used as a long range sword, capable of piercing steel.

Short Range
Unlike similar techniques which are just chakra concentrated into the palm, this jutsu uses pressure to build up strength. First, the user generates Lightning based chakra around their hand and then pulls their arm backwards whilst adding more chakra and building the pressure which acts to concentrate the chakra and make the technique more powerful. Upon hitting the target, the pressure is released, further penetrating the target and adding a small, extra damage radius around the technique.

Long Range
When used as freely extendible/shrinkable sword, the user follows the same steps to initialize the technique except that the pressure is constantly maintained to keep the chakra concentrated into it's shape.

Drawbacks
The primary drawback lies with the Long Range version where maintaining the pressure in high states for long periods of time can damage the user's hand.
