The female counterpart to the ninja. Although trained in the basics of ninjutsu, the training of the kunoichi focused on the less tangible aspects of warfare -- psychology, intuition, and manipulation. The most reliable forms of attack for the kunoichi were surprise attacks to fleshy spots or pressure points, often utilising hidden blades or ornate hairpins, or even musical instruments or sex toys that hid or could be transformed into weapons.
There are two types of kunoichi:
-A "shimma kunoichi" is a member of the ninja family, trained for her specific role. She typically worked under a kantokusha, or a commander, who usually tried to give her the impression she was his only kunoichi. Due to their highly emotionally sensitive natures, the kunoichi needed to be carefully handled so as not to fall in love with the target or lose sight of the goals.
-A "karima kunoichi" were usually hired only for a specific job, acting as a spy within the enemies walls. These women, usually maids, mistresses, or entertainers with access to the house may be purchased for the right price.
The kunoichi could often be used against the targets water-aspect need for sex, though I don't think that makes them masters of manipulation...
Similar to a trowel, the kunai is a wrought iron multi-purpose tool originating in the Tensho Era of Japan (1573 - 1592). The kunai blade was unsharpened, soft iron, and was used for digging, prying, and smashing wood, plaster, and the like -- which would like have destroyed a tool which was sharpened or heat-treated.
While generally a leaf shaped blade atop a handle with a ring at the end, the kunai come in a number of different varieties, including short, long, narrow, wide, and saw-toothed. Due to the nature of ninjutsu's training with improvised and unusual weapons, the kunai became popularly associated with ninja (shinobi no mono), who might have used it as a weapon in disguise.
The kunai -- Japanese predecessor of the Swiss Army Knife.
A significantly obese person, usually a woman. So named for their inability to rest their arms parallel to their bodies, and their shuffling walk.
