Flytanium Zenith Trainer 2.0 1385GGS Stonewash, Gunmetal Gray Aluminum, balisong trainer

The ‘stonewash’ process was chosen for the finish of this blade. The stonewash process involves the blade being placed inside a drum with ceramic stones, or media, and then vibrated or tumbled for several hours. The result is a finish that looks precisely polished or roughened depending on the version. The advantage of stonewashing, however, is that signs of use are much less noticeable. That makes it a popular choice for knives that see a lot of use.
