The sakasa kebari is considered the iconic fly of tenkara. I dig it. The way the reversed hackle flows in water is great and seems to entices fish. I have yet to fish it, but I soon will. They work well for bluegill and bass so I'll have a hay day with my 5:5! All you need is hackle and thread. I love the look of pheasant on kebaris. Not sure what it is, but it just seems to fit! My favorite is the one in the center. It's made with pheasant and a greyish blue thread that I found in my grandmother's sewing kit.
