Knife blade dangle earrings...
I bought an ebay lot of pocket knives to make necklaces. The collection included loose blades and many unusable knives. They looked like they had spent years submerged in a tackle box full of water. After a bit of percolating, here's the happy solution, just in time for Halloween. I dulled the blade, not a small task, but they are to be worn at your own risk!
