The Deep Blue RK-200 Fish Tamer / Ice Breaker has been in use world wide to help subdue and humanely dispatch fish for eating. Works great as an ice breaker or any use in the boat. It’s flat so it wont roll and since it’s made of marine polymer it will never corrode or break and the best part is it floats. Every boat needs one of these handy tools. Lanyard included. Covered by Deep Blue’s Lifetime Warranty.
