Strings had set up most of the perimeter and was almost ready to make it active. If some one came in or went out the wrong way, at least ten daggers would fly straight at them and hurt, if not kill them. These special dagger had a hoops at the bottom of the handle, followed by a sharp hook. When a person trips the wire, the hook would cut the normal string and send it flying in the appropriate direction. There were around eighty daggers total that cover all possible ways to reach them, only one direction had a trick to safely pass through unharmed.  This was the way he was going to use when he would sneak off later that night.
