The Gamakatsu Shiner hook may look a bit weird, but there is nothing weird about how good it is to catch a variety of fish species. The shape of the hook will help present a whole un-peeled prawn in the position you would find it when a prawn is trying not to get eaten.
If you have never used one of these styles of hooks before, it is very easy to get the prawn onto the hook. First, start the hook under the prawn tail, then follow the bend of the prawn, with the hook point protruding from just under the prawn's head.
You could also use it on live prawns, when it is just a matter of putting the hook through the second back of the prawn. This will allow the prawn to kick like it normally does when trying to flee.
