Due to its ingenious keeper feature, the Ruthless Slim Keeper jig head also allows you to slide more narrow jigs onto the jig head without damaging the jig. The quality of the jig head has been improved further for 2020 with new molds and rotational casting. Slim Keeper retains its shape and the material ensure that the jig stays put while fishing. The keeper also does not tear the jigs when replacing them, thus ensuring that the jig detached from the hook is still fully functional. Slim Keeper jig heads are made with chemically sharpened, super sharp Kumho hooks. The forged wire increases the hooks’ torsional resistance and allows it to maintain its shape. Slim Keeper is also available with #4 and #6 sized hooks, which make it perfect for micro jigs.
