The droplet pendant, the star pendant, and the block necklace on Stimtastic are also recommended for light chewing, as well...there also used to be a "footprints" pendant that had "toe parts" there were malleable and good for chewing, but I think it sold out some time ago.
Hope this helps.
It took me a while to find chewable items that worked well for me, too.
