so me and my boyfriend went to the river and found a small island where everything gets washed up to I'm guessing because of the dead animal skeleton and sunglasses and trees that were washed up there. I came across a blade in a wooden sheath that has leather on the outside and was sewn together with some kind of thread. The handle of the knife had been broken off and there are symbols carved in the blade that look like they were hand carved. I need someone to point me in the right direction on what to do with/about this.
