I bought a set of 4 razors off ebay for a very reasonable price. Almost all of the razors have a mirror finish, and one razor which is marked as "Indian steel" has some black marks and a small nick in the edge.

I've also got a norton 4k/8k which I've lapped by following the guide(1). I drew the grid onto the 400git sandpaper and did both sides 4 times. Then I did the 800 grit for 2 grids.

When I attempted to hone the razors, I them up and down with the circle method (2). 40 circles with firm pressure. 40 circles with light pressure. 10 strokes with no pressure. After that, it couldn't cut arm hair, which I heard it was supposed to.
After that, I did the pyramid method (3), and by the end of it, I could actually run my finger down the edge of the blade and not get cut.
