Brief Description:  The medieval kunai was a small, versatile Japanese tool often repurposed by shinobi (ninja) into a concealed weapon. Unlike popular portrayals of it as a throwing dagger, it was primarily a heavy, unsharpened, spade-like utility tool akin to a metal trowel or small crowbar.

Key Anatomical Features:

Blade: Typically leaf-shaped or spade-like. Forged from thick iron rather than steel, it was built for durability. The edges were mostly blunt, used for smashing, digging, or prying, while only the sharp tip was used for stabbing.

Handle: A solid metal shaft with a distinct ring (loop) on the pommel.

Grip: The handle was frequently wrapped in cord or rope, offering a sturdy grip in wet or muddy conditions.

Combat: Primarily a close-quarters thrusting and stabbing implement used in tandem with martial arts to strike at vulnerable joints and pressure points.

Rope Use: The pommel ring allowed it to be attached to a rope, enabling it to be tied around the body for concealment, strapped to a stick as a spear, or swung like a makeshift rope dart.
