Some Blackjack stainless steel models that may work for your purposes.
(1) Blackjack Marauder, if you can find one (IIRC models are MK-1, MK-1a, Reinhardt Khukri, and the 14" long MK-2)
(2) Blackjack Quick (AUS-8, 10" blade)
(3) Blackjack Grunt (AUS-8, 5.5" blade)
The Blackjack Marauder MK-1 is pretty neutral and quick in the hand, which is a characteristic I remember from my work with a BK-7. Which is odd for the MK-1's longer blade length. The relatively thin stock (compared to heft of Busse 1/4-inchers) and saber grind gave decent penetration when chopping with the MK-1. The handle reminds me of the Busse Basic/old Swamp Rat/ScrapYard handle shape. Picture below of a MK-1, below a Becker BK-9 Combat Bowie for size comparison.
I can't speak about the Quick or Grunt models, since I haven't ever handled them.
