Ninjastar - Hira Shuriken / Shaken

Hira Shuriken / Shaken

Hira-shuriken are constructed from thin, flat plates of metal derived from a variety of sources including hishi-gane (coins), kugi-nuki (carpentry tools), spools, and senban (nail removers), and generally resemble popular conceptions of shuriken.

They often have a hole in the center and possess a fairly thin blade sharpened only at the tip. The holes derive from their source in items that had holes – old coins, washers, and nail-removing tools. This proved convenient for the shuriken user as well, as the weapons could be strung on a string or dowel in the belt for transport, and the hole also had aerodynamic and weighting effects that aided the flight of the blade after it was thrown.

There is a wide variety of forms of hira-shuriken, and they are now usually identified by the number of points the blades possess. As with bo-shuriken, the various shapes of hira-shuriken were usually representative of a particular school (ryū) or region that preferred the use of such shapes, and it is therefore possible to identify the school by the type of blade used.

Famous quotes containing the word shaken:

    There are two things which cannot be attacked in front: ignorance and narrow-mindedness. They can only be shaken by the simple development of the contrary qualities. They will not bear discussion.
    John Emerich Edward Dalberg, 1st Baron Acton (1834–1902)
