Concealed weapons excelled in appearing to be unarmed and unprotected at first glance, and were the most suitable weapons for the ninja, who basically acted covertly.
Typical concealed weapons include the tekko-gagi and nekote.
What is Tekko-kagi？
Tekko-kagi (as in the drawing above), a hand grappling hook, is a weapon that attaches a sharp, claw-like blade to the back of the hand. It was also used as armor to attack by cutting with the claw part or to stop an opponent’s sword attack with the back of the hand.
In addition to its use as a weapon, it is also said to have been used to infiltrate enemy territory by driving the hooks into walls and trees to climb high places and dig holes in the ground.
What is Nekote?
Nekote, meaning cat’s paw, is a sharp, claw-like cap attached to the tip of the finger.
Because of its small size as a weapon, it can only inflict damage equivalent to scratching.
However, it is thought that they compensated for their weak offensive power by painting their claw tips with poison.
