Chakra Manipulation: Chakra Extension Blade/Edge

This jutsu is similar as samurais in the Land/Country of Iron using their chakra to increase their swords' edge length, when they was trying to take Sasuke and his group down. But this jutsu is also different as it can be used on ANY weapon, either sharpen, harden, increasing its density, longer range of length, lighten its weight, increasing its offensive or defensive, etc. It can also be used on body armors though only few Shihai-Gamen members wore armor.
