Hey guys,
I think he's talking about edge finish, not sharpness.
This is what I do on my multiblades, although I don't really like the stockman pattern because of the proud sheepsfoot blade, usually the main/bigger blade is finish around 600 grit (fallkniven DC4 diamond side) + strop on bare leather(fallkniven DC4 sheath) because is a great compromise between slicing and push cutting abilities.
On the secondary blade I try to keep an all the way polish (to 8000 JapWS + strop with flexcut gold compound) because I use this blade for push cutting (plastic, whittling wood, etc)
On a dedicated whittling pattern I keep the two ssecondaries polished
I also have a D2 queen muskrat pattern that is my edge experimentation knife, because you have the same geometry on two blades in the same package. So I keep one 325DMT very coarse and the other 1200DMT + ceramic + strop and then cut the same stuff with both to compare, and yes I'm a kind of a sharpening knut
You can use the edge finish to enhance the properties of the different blades, for example the spey usually has a very fine grind and I like to pair that with a laser like polished edge for detailed cutting. But the best advice is try it yourself and see what you like
