I carried this
TOFERNER Celtic/Norse/"Viking" pocket/neck knife daily from 11-04-21 to 04/28/26, 24/7/365.25 (less about 2.5 hours shower time over the 5 years)

I modified the sheath, adding the tuck-in flap. The blade length is 58mm (same as a closed Vic SD Classic/Signature/Mini Champ).
Toferner has other Medieval style pocketable fixed blades. All are "Affordable". I paid under $20 for mine, with free (not "prime") shipping, on the "big river" site.
All have the "As Forged" finish. Several have leather wrapped handles. Blade steel is a good, tough, Czech carbon steel, with an excellent heat treat.
Admiittedly, I carried this one mainly as a neck knife, but I did carry it in my pocket a few times in the oem sheath, and on my belt, in a leather sheath I made for it.
On 04-28-26 I swapped the Toferner out for this David Mary "Itty Bity Bitey Birdie" (his model/pattern name) pocketable fixed blade that was gifted to me a couple years ago, by a generous member here. I don't know yet if I will carry the David Mary as long as the Toferner.

As you can see, I added a cord to the Kydex sheath for neck carry.
I do not have one yet, but CRKT makes a few small neck/pocketable fixed blades that are stainless.
The Mora Eldris might be another viable option.
