Here’s an inexpensive tool to put down tuna headed for the fishbox. Saw off a sledgehammer handle to 18 inches long and drill two parallel 5/16-inch holes at the top. Then insert two stainless-steel carriage bolts – select bolts two inches longer than the thickness of the handle, so they stick out – through the holes. Fasten the bolts with washers and self-locking nuts and then sharpen the bolts with a grinder. I can put a fish down with one swift blow.
