A safety shackle has a threaded pin that threads not into the shackle itself, but a nut on the outside of the shackle. The pin has a hole through which a cotter pin is run through. The shackle develops full strength as the pin is full diameter going through the shackle body. A Jew's Harp is such a shackle and it amazes me that all the shackles, "safety" or otherwise require mousing. Is there a reason for this?
I looked up a couple of references and they are contradictory between
the ring and the shackle and in one case both, but if you think of the design
of the instrument then you can see the shackle similarity. Shackles are an
interesting bit of hardware. I've been buying some of late that are the captive
pin variety and man they are miniature works of art. By that I mean they are
quite beautiful and cost half the national debt.
