This spinnerbait has a bit of a unique trailer keeper, or a different one at least. There are probably a few other baits out there with a similar one but none come to mind. Where most spinnerbaits have a trailer keeper with one big barb sticking up, this spinnerbait has sort of a ribbed keeper.
I like jigs, spinnerbaits and buzzbaits with the big barb keeper most of the time but when using a thin soft plastic as a trailer for a spinnerbait as I will do at times, those big barb keepers will often tear the thin plastic really easily and you have to replace your trailer a lot more. With this ribbed-style trailer keeper, you run into a lot less of that.
