Steel Release: Stahl Herz

Steel Release: Stahl Herz is a supplementary Steel Release　technique that increases the defensive and durability of the steel. This is done by adding steel nature chakra into the created steel to strengthen it. This can also be done by manipulating ones chakra to mold and compress the precious minerals found in the ground to create steel. This technique can be very useful in a battle since the user can increase the strength of the steel to counteract the opponent. However, the stronger the steel, the heavier and slower it becomes. As well, it tends to drain more chakra compared to lighter, weaker steel. The user can also weaken the steel by removing steel nature chakra from the created steel. However, the user is unable to reapply the steel nature chakra once he or she takes it off. The user can also use this technique on man-made objects such as pillars, defensive walls, ninja tools, and armor but the man-made objects must be comprised entirely of steel or variations of steel.

Trivia

 * Much like the nature transformation Storm Release, some of the Steel Release jutsu have English names that uses kanji to somewhat match them phonetically. However, unlike the Storm Release, it is in German instead of English.
 * Stahl Herz means steel heart in German.
