Pivot Pin Collars

[Peck]

After looking at the pivot pin collars that RickKrung made I started thinking. What if you put a 12mm wide flat bar to hold the knife flat against the stone to prevent swale by holding the edge perfectly flat against the stone. The round stock would still allow you to rotate to sharpen the curved end.  Is there a draw back that I am missing before trying to make some of these?

Please elaborate, perhaps with a diagram or photo of a mock-up.  I am not envisioning what you are attempting to describe.

90 degrees from the round stock you have welded on the collar . I was thinking of doing a rectangle stock 12mm x 45mm parallel to the knife edge.

I'm with Rick... guess I need to see it.     I envision something flat coming out that would ride on top of the USB to hold the knife flat?  (Then I wonder why it has to be 12mmx45mm...).

Would have to see to understand, but in general, even though you don't really "lift" if you rotate the knife, you do a little, if for no other reason than allowing the handle on some knives to clear the USB.  You also need a little bit of freedom to work recurves, maybe grind a small area near a bolster, etc.

But the picture in my head could be wrong.  Duct tape something together and snap a photo.
