Okay, here was my other design proposal all those years back. This one was a definite no go as Peter had told me the Tusk was apparently on the drawing board even back then. I didn't know it was the Tusk at the time but he told me Sal already had a rigging knife design that had been around for a while.
My concept was to do it as a Slipit since rigging knives traditionally were slip joints, and it would allow more universal sales in places where locking blades are prohibited. Which I thought might be handy if you were a sailor traveling between ports. For more general use I also thought it would make a great woods folder. I love the marlin spike for working with knots and find it handy for poking at stuff that I don't want to risk poking at with the tip of the knife blade
I think once again I found a weird niche that I thought was handy but in hindsight wouldn't end up having enough universal appeal to really be considered. But my buddy Tom did another amazing job rendering my idea anyway so here it is
