Happened to have nothing to do for the moment and even though I'd previously responded to this post I thought it would be interesting to point out a couple of items. Z-Man's patent actually covers the specific way it attaches, i.e., thru the actual hook eye. They know they cannot claim "rights" to the blade itself nor can they claim infringement if a blade is attached to a bait using a split ring or other configuration. Now they can "bully" and send copies of their claimed proprietary rights and most will acquiesce (and rightly so) but if they ever come up against the big boys my sense is they'll loose. Does anyone remember Uncle Buck's Tornado Spinner Bait? It was designed by "Shoestring" DuBois and featured a blade (they called it a clapper) attached to the spinner bait which caused it not only to flap and wobble but also make noise via its attachment to the frame. Shoestring claimed one could use it as a spinner bait or a buzzbait, it all depended on how fast one cranked it in. The prominent feature of this lure was the "blade" and other than the bend, it's basically a Z-Man blade. Any comments re this analogy? Wish I could find a pic of the old bait, Bass Pro no longer stocks them and I've googled it to find a pic, to no avail.
