Picked up some Magpul MOE rail sections for the hardware (will run an aluminum rail, when the time comes). The plates on the back will be perfect for distributing the weight of the optic on the pot metal top cover, and will also get bent in the vice to provide a rounded foot, once I get that far.
Found 3D print files for the knife and Kilrogg droid here:

The droid is free, the knife is a buck and a quarter... But since this saves me days/weeks of modeling, I'm very much not opposed to paying.
I scaled the knife to 0.75 before printing. Glad it's a huge model, but I think the original scaling might be way too big. We'll see when this print is done. The droid will get magnets and LEDs to keep it in place, etc.
I have come across a few real steel knives (harpoon or "bird and fish" knives) that are so very similar, but none exact (handle and jimping on the spine of the blade). If anyone knows where they got the knife, I'd love to hear! Otherwise, I'll have to have my bladesmith friend make one.
[edit] The knife print is done and looking fairly okayish!! It should be enough for me to get my bladesmith friend to copy it in steel. 0.75% scaling looks just about perfect!! It's just right in the hand, and looks pretty dang close to screen-sized when gripped like I'm about to throw it at a wookiee.... [/edit]
