A great user knife with a satin finish and micarta grips at 5 inches is the Koster Bushmaster . It's 3V. More an alloy steel than true carbon ( 1060, 1070, 1980, 1095). It will resist corrosion pretty well as long as you take care of it so no changes to the steels finish is needed.
I bought a Big Chris Bushcrafter in 4V that is a bit shorter than you want. I know he makes some in 5 inch range and in several steels. Anything Big Chris is worth a look, and more IMO.
Like Phil Wilson he will get all the performance available in whatever steel he is using. You can count on that.
