The Hardytack Craw was designed by Jim Hardy and Braxton McNaughton exclusively for NetBait. They wanted to create a bait that would look, imitate, and move just like a real crawfish. There is a bubble about three ribs from the twin tails that lets you know where to thread the hook into the craw. When rigged this way it allows the twin tails to swim under the Hardytack Craw and simulate the swimming action of a real crawfish. The best head to rig it on is a bare Paca Bug or a Paca Bug with only the top half of the half. You can also easily pull off appendages and make it into a swim jig trailer, traditional craw trailer, or a punch bait.
