Entering a Water Obstacle

This [tool] is used for stealthily crossing a moat [or any water barrier]. Use iron for making the upper round section in the shape of a helmet to be placed on the head. Attach a string on both sides, and at the end of each attach a thin iron plate. It is possible to cross even a fast flowing stream by holding these plates.

Also, if a person is hitting from above, it will not reach the head. Or if arrows and stones are shot at the helmet, they will not penetrate it. It should be good to temper the iron. You should hold the two strings in your hands.
