Are the ends of the pin exposed on both cheeks?

If so, cut the pin off nearly flush with the interior of the throat.  Drive out
both stubs with a wooden drift.

Through-drill a replacement pin center and then shape it to properly grip the
blade. ( Easier to grip if drilled before shaping. ) Use a drill press to keep
the hole parallel with the axis (Galootish post drill or Yankee hand cranked
drill press. ) Note that this will be the same flatted shape per Krenov.

Gently drive a brass axle through the whole assembly.  Everything should be a
press-fit.

Bob’s yer uncle: you have Flatted pin to grip the wedge, pressed onto a
replaceable brass axle which will never break unless brutally abused.

Who admires Krenov’s flatted pin which gives a much better grip on the wedge
than a round pin ever could.
