As I've recently learned to hone razors (as in last weekend), I have some idea of what it takes to get a razor sharp. The razor that I learned to sharpen was a Dovo 300 - with the note that it was factory sharpened and "shave ready."
I'd like to reiterate what Philadelph about shave ready - they don't or rarely do...
When I was honing my Dovo, it already had a bevel set, so I started on a 4K Norton. After quite a few passes - to make sure it started popping hairs, I then changed to honing on a 8K Norton. When that was sticky sharp, I started polishing the bevel on a 16K Shapton. After 8 or 10 passes, I stropped on a felt pad treated with .5 micron diamond, followed by stropping on a leather strop.
Last night I shaved with that Dovo and it was "scary sharp."
