Throwable Japanese hidden weapon A (Japanese:; literally: "hidden hand blade") is a Japanese hidden weapon that was used as a covert dagger or metsubushi to distract or misdirect. They are also called throwing stars, or ninja stars, although they were originally developed in several shapes. The major varieties of shuriken are the b shuriken (, stick shuriken) and the hira shuriken (, flat shuriken) or shaken (, wheel shuriken, likewise checked out as kurumaken).



Bo-shuriken [edit] A Bo-shuriken is a tossing weapon including a straight iron or steel spike, typically four-sided but in some cases round or octagonal in area. Some examples have points on both ends. The length ranges from 12 to 21 cm (5812 in) and the typical weight from 35 to 150 grams (1.
4 ounces). The Most Complete Run-Down must not be puzzled with the kunai, which is a thrusting and stabbing carry out that is often thrown. Bo-shuriken were built from a wide range of daily items, and as such was available in numerous shapes and sizes. Some obtained their names from the materials of which they were made, such as kugi-gata (nail kind), hari-gata (needle kind) and tant- gata (knife kind); some were named after an object of comparable look, such as hoko-gata (spear type), matsuba-gata (pine-needle kind); while others have names that are simply descriptive, such as kankyuto (piercing tool type), kunai-gata (energy tool form), or teppan (plate metal) and biao (pin).
The major throwing approaches are the jiki da-ho (direct-hit technique), and the han-ten da-ho (turning-hit technique). These 2 are technically various, in that the former does not allow the blade to spin before it hits the target, while the latter requires that the blade spin. Four antique created Japanese bo shuriken (iron throwing darts with linen flights) Other items such as barrettes, kogata (utility knife), and chopsticks were thrown in the same way as bo-shuriken, although they were not related to any particular school of shurikenjutsu.
This is partially since shurikenjutsu was a secret art and likewise due to the fact that throughout early Japanese history there were numerous independent exponents of the ability of tossing long, thin items. The earliest-known referral to a school teaching shurikenjutsu is to Ganritsu Ryu, active throughout the 17th century.
