No two hunters activate their edges in the same way, even if they seem to have the same powers. Some people need to get sufficiently angry to manifest desired edges. Some think back to the moment they were Imbued and call upon those same emotions to summon the edges they need. Others learn to trigger their edges by saying certain phrases - a trademark of sorts. Hunters who wrestle morally with their powers may need some prop, such as a religious icon, to activate edges - items through which powers are used.

Your character should have his own triggering mechanisms. He may have one that grants access to any edge he possesses. Each power might have its own unique trigger. Means of calling upon power may not develop until your character has had a few encounters with the unknown.
