Very right you are. The point about the blades I’m showing is that they are hard to repair. I can push a needle through the opening as a trial to reerect the—burrs?—but after two or three attempts, also from the opposite side, in finding a fit I encounter danger of total outfall (hardening-breaking). A comrade of mine here in town spoke of a no-play fit between the dome-shaped crowns and the grooves. Please see picture. As I understand it today that was never intended, the risk of blade slip-away is too big.
Blades, leaves, which is the right term?
We should team for a press, punches, and dies to make fresh leaves with solid pivots. Lens Mechanics or so
