You first pry open the clasp just to the point where the trigger
will come out. Then reinsert the trigger w spring fitted, finagle the
axle ‘nubs’ of the trigger into the detent which you cannot see while
making sure the ou ter end of spring rests correctly in the cutout
opposite the clasp opening and the inner end sits within the trigger
clear as mud, right? Really its not hard if you have the thing in
front of you, its the telling that’s tough. Take it apart, see how it
works, put it back together.
Sometimes the spring may have just popped out of alignment. If its
definitely broken good luck making one, better to rob one from a
same style/size silver lobster. Be careful not to cinch it closed too
hard. How hard is too hard? When it doesn’t work anymore you’ll know
how hard not to go next time.
Or you can sell a new 18K lobster.
I vote the second option.
