Thank you fellows for the pictures and links.

Is it a "gnat" because it is handmade? I have jigs that are store-bought that look very similar to these you are showing me. Are the ones I have gnats, or just plain ole jigs? They say jig on their box.

How you would delineate a gnat? I don't know that it matters really, but I like to know what folks are talking about. I have always heard that the only dumb question is the one that isn't asked, but I do not entirely subscribe to that line of thinking.
