Ninja Climbing Gear
Historically, Ninjas were excellent free climbers, and also had a variety of specialized tools to help in scaling walls. Shuko, or hand spikes could be used in climbing as well as a weapon in hand to hand combat. Likewise, Ashiko were spikes attached to the feet that could be used in climbing, as a weapon, or to provide traction on icy surfaces.  A final tool that is very useful for climbing is the grappling hook. Originally developed for use in navel battles, a three or four pointed hook can be used to place a rope, either for ascending or making a quick escape.
