greets all.
long time listener / first time caller.

i'm not really new to SR shaving.. but am just coming back to it.
Lets say I'm re-acquiring my appreciation for it.

Sort of started when, on a whim, i picked up a 'shavette' style
razor (was just there staring me in the face).. a Muster (?)
brand.. and a pack of Feather DE razors.

Having a great time / can get a really good shave in ~10 mins.
Was sort of like riding a bike.

So broke out my old kit: 5/8" Mehaz Solingen and old Little Devil.

Got a new strop.

The Solingen was a little worse for its storage but after some clean up
looks (almost) good as new.

Thing is (sorry so long winded).. I can't get it as sharp as the
shavette with the feather razors.

Question: is "as sharp as a feather" a realistic goal? is that possible?

I'm using water stones.. highest I've got is 6k. I *think* that should do it.

The solingen doesn't really "tug" .. but its definitely more force than the
feathers.

Should I got to 8k stone? 10k?

Funny aside: my Little Devil actually feels (and sounds!) finer than my 6k
waterstone. Is this even possible?

Not using any compounds on the strop.. just a dozen or so passes on
webbing side.. and another dozen or so on the leather.

Thanks!
