How do I use ninja shuko and ashiko?

Well, I just got some new ninja climbing claws and foot spikes, but i dont know exactley the rite technique to use for climbing..say a tree? so if you%26#039;ve got any information please let me know.|||that is like buying a BMW and not knowing how to drive. I guess just try them and hope a cop does not see you because that would be destoying public property|||Find a good ninjutsu school to learn how to use them.
