Wire shaping jig

Is anyone using a wire shaping jig to "standardize" their wire bending, specifically related to balsa crank baits? If so, could you share your thoughts as to their effectiveness over hand bending each wire (I am afraid each of my lures is truly unique-and not always in a good way). Also, if you have used a commercial product or made your own.
Thanks,
Dave

Check out the Engineered Angler on YouTube. He has a ton of videos and a couple on wire bending jigs he has made. Pretty easy to make.
