even though you've already chose, if you looking for an exact aurora package, then your looking for a modified sar5.
If you send one to the custom shop, I would suggest shortening the handles (remove the butt end), making new scales so they are farther forward, and slimming the blade down with whatever grind you want.
The knife will spend anywhere from 3 months to a year in the shop, if all goes well 4-5 months, and will cost between 75 and 200$, probably closer to 125. in the end, you'll have a one of a kind custom thats well worth the wait.
heres a link to the one I had done (though I modified the pommel and the handle material to be like this). it's in link form instead of img because it's kinda big.

the sar5 is a great customizable blade, and is reletively affordable at the moment for how big it is.
and personally, I'm a huge fan of the rat tail. I like the ratmandu, but I can't stand the choil. the rat tail is small, no frills, pocketable, small choil, stout enough to pry with but not so thick it's unusable. and reletively cheap.
