This is a very unusual and bold design. In the same time, it is very interesting and appealing to the eye. You can see the fish skeleton, with a human skull on the front.
Reason for someone to choose this design is the strong symbolism behind it. It represents the self-sufficiency that is often associated with surviving in the wilderness. Often by fishing for food. Fish is a strong symbol in the Christian religion. It defines the wearer as the follower of Christ, who has an adventurous, outdoorsy persona.
The skull is the main symbol of mortality and death.
