Lesson Learned!

I won't bother disassembling the Merkur 34C handle for cleaning and maintenance again!

Not a fan of the internal tension ring design. Lovely trusty little razor but that ring expands too far apart upon release to be squeezed back in by hand. Fingers were jammed and every time the handle dislodges the ring, it gets whacked further out of shape!

The answer in the end was to squeeze it back into place with a pair of small pliars. If you guys find yourself with the same problem, that's what to do.
