Thanks for all the replies and insights!
I understand the sliding scale of getting what you pay for, so to speak. I used fairly inexpensive knives for some time, a used Kershaw Scallion being roughly the top of my scale. When I purchased a Spyderco Native I thought - whoa - this is a fairly significant upgrade in terms of overall fit, finish and feel. Then I picked up a Spyderco CalyIII and while the Native remains a favorite weekend and task knife, the difference in overall fit and finish between it and the Caly III is noticeable. Again, the Native remains a favorite knife but the Caly III is just a better overall product. I can see similar issues between a good knife (Bradley) and a great knife (sebenza).
Having looked at the alternatives, well, I have to admit that while not exactly a Sebenza the titanium Spyderco Sage is a pretty sweet looking knife - and given the somewhat in between a CalyIII and Native blade profile (both of which I obviously like) it is a compelling alternative.
still - I'm thinking perhaps holding out is a wise option as well and getting what I really want!
