I've been wondering why I've never seen a nut and screw used as a pivot point for a straight razor. The nut could have a small lock washer and would be countersunk into the scales. The advantages I see for this is that the setup would allow easy removal of the blade for cleaning/polishing, and would also allow for tightening loose scale-fit when needed. Is this something I've overlooked? Is it a tradition thing to go with pins only? Just askin'.
