Kunai were often used as multi-purpose tools by craftsmen of the feudal Japan. Therefore they were ideal for Ninjas to utilize them as disguised weapons. The Kunai was used as throwing knife, break-in tool and even as spear tip. The metal ring on the downside could be used as mounting or as weight for hard strikes.
This weapon is made of an extra durable PU foam, that is also super soft and bouncy. It does not have a fiberglass rod and no extra weights inside.
You can get it separately and in sets of three or ten.
