The original persian with a ball bearing lock blended into the bolster so that it doesn't mess up the flow of the knife but as beefy as possible, screw or hex construction, open back bolsters, low riding wire clip made of matching pattern of the blade and handle in wootz or damascus.
Full flat grind blending smoothly back in thickness so as to blend the unground bit of blade instead of having the ramp up. Perhaps brought out a little bit bigger to 3.25 to 3.4 length with a 13 or 14 mm hole, whichever fits more smoothly. Wootz patterning look or raindrop damascus sorta steel made out of h1 MAGICALLY so that it can't rust and is also very hard and tough in equivalent to H1 but wont chip with a matching grey shaded to black patterning on the g10 handle, maybe make the patterning designs of grey shading slightly indented so as to create more texture so that it is quite grippy.
Oh, and jimping on the thumb ramp, maybe in some cool pattern.
