Hello gang-
Just a few thoughts: I really don't think they were used for grain sacks etc.- the self-closing mechanism (or whatever you call it) would puncture the sack, hence spilling the grain or hastening its exposure to mold or other icky things. Here, I speak from experience. And meat hooks are longer and pointier, sans mechanism, and much thicker than what Mojjax (sp?) has presented. Very very different. As to hanging pots & pans on a ship, maybe, but it would be a big pain in the dupa to get your pots down while fiddling around with the closing mechanism. Also you see pinstriping/decotation like that on Eastern European stuff too- Polish, Lithuanian, Croatia, etc.
Party On,
