There are literally thousands of choices when considering a fixed blade knife. We at Survival Think Tank are knife nuts, and love our high end blades for sure, but we also respect a quality knife at a great value.
In the novel, Tunnel in the Sky (Heinlein), we are bombarded with the importance of a fixed blade knife in a survival situation. Once you read this book, you'll never get too far from yours. As a gift for your son or daughter, we would recommend purchasing them a copy of this novel and shortly after, a good fixed blade knife.
