More About Kunai:

A kunai is an ancient kind of trowel, originated during the Tensho Era in Japan. The kunai was normally wrought of iron, not steel, cheaply forged and unpolished. The kunai was used by common folk as multi-purpose gardening tools and by workers of stone and masonry. The blade was soft iron and unsharpened because the edges were used to smash plaster and wood, to dig holes and to pry. Normally only the tip would have been sharpened. The uses to which a kunai was put would have destroyed any heat-treated and sharpened tool like a knife. Contrary to popular belief, they were not designed as throwing weapons, though they can be thrown and cause damage. Instead, they are a thrusting and stabbing tool. Kunai normally had a leaf-shaped blade and a handle with a ring on the pommel for attaching a rope. This would allow the kunai's handle to be wrapped to act as a grip, or when used as a weapon; to be strapped to a stick as an expedient spear, to be tied to the body for concealment, or to use as an anchor or piton.
