Sorry, but I do not have one. I do have the Rukus in plain edge and pewter finish. I can say that in this format, the Rukus is a real winner. The flat grind allows it to slice and slice and slice, while the S30V steel allows it to hold and hold and hold it's edge! I've read that a few folks don't care for the length or girth of the handle, but I've found it to be just right for me. I've carried this knife as one of my edc's for the past month, and it rides in my right front pocket without difficulty.
I think that serrations would affect the slicing ability a little and for that reason I will not get one. But with it being the newer BC-1 coating, I will get a 610 BK when available.
