Hey, it gets the job done, right?
For style, though, what Faruk Ekich came up with is simply beyond elegant. I have been a fan of Damascene steel for years (I did silversmithing for a long time - what this guy does is what a master blacksmith can accomplish - usually only seen in extremely expensive knife or sword blades). Most know him for inventing the Ekich bobbin.
The pattern he used for the adjustment knob is the shape of the wings of the 3 most common flies people tie - stonefly, caddisfly, and mayfly. Saw these in a recent Fly Tyer and was so intrigued.
