Shape based on the Daiwa SP minnow but the cross section is more square than oval. I was watching a tutorial (on proportional spline) video on YouTube and the guy (David Brown from Hawk Ridge System) has this organic shape and thought it was cool so I decided to make a lure out of it. I have another lure with a triangle shape minnow and will upload later on. I've added a bunch of holes for weights at the bottom in case someone wanted it to sink.
