Thanks again, folks. Pumblerdv, thanks for the picture - that helps a lot in getting a feel for the sizes. The picture also reminded me that I did have a Koji at one time, but sold it. It was just too bulky for it's size, although it was a beautifully crafted knife. I'm still gravitating towards the 525, but we'll see what I finally come up with...
BTW, I have to say that you folks in the Buck forum have to be some of the most helpful and friendly BF members around. Very nice!
