This is Restoration... See it is pretty easy to do the "Oh just wipe it with a rag and polish dance" right until you start and find that under there is where the work begins :rofl2: First thing is to "Tune up the razor" hehehe since it is a Hollow grind hold it near your ear and use your thumb to pluck the edge, that singing sound is what you always want to hear.. Try it near the toe in the middle and at the heel, remember it...
Go back to the 320 grit and settle in and start sanding, I used to start with each grit dry, then at the 400 grit level I would start dry, then spray WD-40 on the razor and keep sanding, it helped to create almost a slurry and that got me better finishes with hand sanding..
Stay on the 320 until one of two things happens,,,
1. You get rid of all the crap and get the look you want
2. You sand for hours and "tune" the razor and notice that the song went flat, that means yer done, you have reached the maximum you can take that edge down to...
Progress up through the grits and polish out, switch to a compound like MAAS, Flitz, Semichrome, Blue Magic etc :etc:
That should get you to where you need to be and the razor is ready for the hones
ps: There are more tips & tricks along with all this info I just typed in that link I gave you above
