Hand seals, also called hand signs, are used to create many Ninjutsu , Genjutsu , and other secret arts other than Taijutsu . There are different sequences of hand signs for every technique, requiring memorization. While techniques may require a number of hand signs to work, a skilled ninja can use less or even one to perform the same technique. An example of this is the Water Release: Water Dragon Blast Technique , which requires a total of 44 hand signs to activate. Timothy however didn't use any hand signs to complete the technique, a testament to his skill.
Besides the 12 traditional hand seals, each named after an animal of the Chinese zodiac , there are unique hand seals used for few techniques. These hand seals are rarely seen, and can be considered unique to specific jutsu.
