Boomerang for recreational throwing. I have included two versions, the second one being slightly more streamlined to reduce drag. I would recommend the regular one for windier conditions and the streamlined, "less-drag"-version if the other one peters out before making a full return.
Made in Blender with a non-destructive sub-d workflow. Have a look at the .blend file and the modifier stack therein to figure out how this was done.
The author marked this model as their own original creation.
