Using nature as inspiration, Titan Knife Technologies’ created its 812-inch fillet knife to operate on the same principle as a beaver tooth. A beaver tooth has a hard front surface and a soft rear surface. The coating of the 812-inch titanium Titan fillet-knife blade is hard on one side and soft on the other. The softer side wears away faster than the harder one, which allows the knife to virtually self-sharpen. A comfortable ergonomic handle complements the blade’s aesthetic appeal and its functionality. This knife will not rust or corrode and rarely needs to be sharpened. If you would like to hone the edge, all it takes is a few gentle strokes of a knife-sharpening tool on one side of the blade. $79.95; www.titanknifetech.com
