If you look closely at the eye of these hooks, you'll see that it's not round but an oval shape. The oval eye allows you to easily make your own set of ganged hooks, and therefore increase or decrease the number of hooks you have ganged up. The best thing is that it can all be done without the use of a set of pliers.
The unique thing that sets these ganged hooks apart from all other ganged hooks on the market is the shape of the eye.
