Introduction to ninja skills using weapons
The shuriken, a representative ninja #weapon, includes both flat and cylindrical varieties.
Being of various shapes, there are types with four, five, six, seven, or eight sides.
Also, the tip of a sword is short and thus it cannot inflict a fatal wound, but its power to kill could be enhanced in such ways as placing poison on the tip.
There were also others, such as placing a slow match on a flat shuriken to throw at the enemy, metal cones for putting with flat shuriken to throw, or to hold in one’s hand and wound the enemy.
However, if one walked about with these, they would look suspicious, so ninja often used pegs and sewing needles for the same purposes.
Using these to shoot from the cracks of doors, etc., this was an optimal weapon for a ninja who wished to hide himself. Blow darts were normally used for hunting and other purposes, but since the long tubes would arouse suspicion, they used blow tubes as flutes, etc. to avoid detection.
Besides using these for sewing fabric, #ninja also heated needles in fire and floated them on water to magnetize them, or used them as weapons such as darts, and even used them for medical self-treatment. Needles were thus used in a wide variety of ways.
And since they could be held without arousing #suspicion, needles could be said to be the most useful of all tools to the ninja.
