    Microfasteners.....
    That might make it easy to test some things
    if you have not peened them down.

    Think like a machinist and check
    all the parts including any references.

    Do you have washers between the tang and the bone of the scales?
    With microfasteners you can add or remove washers. Even thin shim
    like washers cut from brass foil. The tail of the razor might be oddly
    shaped so washers that minimize and localize the contact area could
    help.

    What you describe may be a small mismatch in pin size in a
    hole that is just a little bit large. There are three holes: each side of
    the scales and the hole in the razor tang to check. Given the
    length of scales a small difference is all it takes.

    Probe for a gap in all three places with a thin shim
    of brass foil and adjust if it bothers you. It would not
    bother me for the most part.

    The other thing to check is the way the scales were drilled
    at both ends and also the way the razor was punched. Anything
    other than a nice clean vertical hole might be the issue. This
    includes the wedge end.

    This is manifest on some of my Razors, I assumed that it was that when the blade first started to move it would rotate in relation to the washers, but that for whatever reason, it then took the washers with it and the perceived friction changed because the washers then rotated with the blade in relation to the scale. No idea why and never thoght of it as a problem.

    Good morning, all. Well, after a good night's sleep I went to the shop to see what could be done with the Boker. I got to thinking about the wedgy shape of the tang and what niftyshaving had said about reducing the contact area of the thrust washers. Since my large thrust washers were superglued in place I opted for relieving the surface of the tang which I did with my trusty Dremel tool. I dug 2 "wallows" on the forward sides of the pin hole and refitted the blade with 1/16" brass rod. Voila! No slack, no drag, no catching...beautiful, smooth action throughout the entire arc. In conclusion (finally), I'd have to say that the original problem had to do with the taper of the tang as it rotated in it's arc around the 2 parallel surfaces of the scales. The large thrust washers exacerbated the problem. Anyway, the Boker is now buttoned up and closer to its delivery with my thanks to each and every one of you who offered your suggestions...all of which had validity and in some way helped to solve this anomaly. Again, thanks.
