Just 'finished' re-honing a razor. The day before yesterday I spent several hours re-grinding this ZY razor so that it would have one bevel (or so I thought). Then set a bur, and proceeded to polish it down to 0.3 micron lapping film. It shaved pretty nicely after that.
There is one area, about a quarter of the blade length on the side of the blade with the logo, where I can see with a jeweler's loupe that the bevel is not taking a polish at the same rate as the rest of the blade - it's a void in the edge geometry. It's not entirely missing out on the polishing process, but at 3 micron finish level, this area still has a scratch patter that looks a lot like the 5 micron scratch pattern. The razor shaved pretty nicely after yesterday's
So, this area was bugging me today. Just knowing it's there is like an itch in my brain. I decided to take it back up to 1200 grit to try and grind this area out. Problem being, it was polished at a finer degree, so once I hit it with 1200 grit, I couldn't see this area anymore. So this afternoon into the evening I did 300 laps at 1200 before polishing it down. At the 1 micron finish, this spot seems to have gotten only marginally better. Polish the blade down to 0.3 micron on lapping film, then proceed with the balsa strops at 0.5, 0.25, and then 0.1 CBN.
The entire bevel looks glassy smooth under the jeweler's loupe except this one area on this one side. This area looks like it was finished at about 3 microns.
The blade is sharp. Even this area, which has the same glassy smooth bevel on the non logo side of the blade, will pop hair at a quarter inch off my arm, though I could wish for it to do so a little more quietly.
So just how perfect do you guys insist your edge get when honing a new to you razor? Part of me is just annoyed that I spent that much effort, and it isn't right... Makes me want to take her way back up to like 300 grit wet or dry, and make it right - run the whole progression again. Part of me thinks that's nuts.
