While teaching himself to use Asuma Sarutobi's Chakra Enhanced Trench Knives, Shikamaru invented this technique to use against Akatsuki's Hidan and Kakuzu. Using the trench knives' ability to absorb the user's chakra, Shikamaru stores some of his shadow in the blades. With this, Shikamaru can target his opponent's shadow and remotely trap them in the Shadow Imitation Technique. This is extremely advantageous as Shikamaru is no longer restricted to a stationary position while holding down his opponent. This charge is apparently independent of physical contact as he was able to restore it with the Shadow Sewing Technique.
