Best 2ndary knife for my BK9 sheath?

[slm9s]

I bought a used Swamp Rat Ratweiller that had no sheath and the seller generously threw in a BK9 sheath which fits great. I searched and there were a few posts about secondary knives for this sheath, mostly the Remora, but the posts are all 10yrs old. Just wondering if anyone found a better knife to put in there. As it's not a Becker knife, I'm not worried about brand.
This will be used for camp uses, whittling/food prep/etc...
Other options I've ran across but not sure they'd fit the small sheath:
Tops 3 pointer
Becker 23BP
Kabar Archeron
Buck Paklite 135ORS
BPS Techno Bee

I'd like to stay under $100. Any experience/suggestions?
Thanks in advance!

It’s a very small opening, the remora is tiny, and not much else fits without some sort of modification. I can’t say with certainty as I don’t know where mine is, but maybe a Ritter/CRKT RSK MK5 might fit. It might not.

Alox SAK?…
Only if you don’t have one in your pocket.
Although, the Remora and a firesteel make a mean combo.

I can confirm the Kabar Archeron fits in the little sheath behind the pocket. Not a fan of the knife but it's better than nothing.
BK23 fits in there. I've seen pictures of it.

I like packing Vic SAKs in those pockets…They add a LOT of versatility to the big blades.

Possibly slightly off topic. But here is my choice.
