Usually when they don't give it a name and it is shaped like that they just call it a hand carved plug or lipless swimmer.I think they really took off after the rattle traps but they wanted a bigger heavier bait that had more of a bunker profile I don't know if they would consider it a slider with the flattened sides.I do know large rattle traps are deadly on just about anything that swims they just need bigger hooks I've caught weaks,blues,stripers,fluke sea robins on them I don't know if its the tight wiggle or the rattles or a combo of both but they work.Especially now on weakies(chrome blue back 1 oz.) early in the morning with the snappers around with a pretty good retrieve let it sink and then just reel it in they love it when they are around that will do it.
