This is a double-sided crook that I modeled a few weeks ago. While it may not be particularly impressive, it features a simple design with both curved portions facing opposite directions, and one side is smaller than the other. It was initially intended for a fantasy mage rather than practical use, and it does have a relatively high poly count.
