I am a new straight razor shaver. I purchased a new Dovo and paid to have it honed before being shipped. I received it in February and after a shave or two touched it up myself. I got a better edge than what I received since then I have touched it up several times with diminishing results.
I finally decided to take it down to a coarser grit, reestablish the bevel and work back through my progression. At 1200 grit I found I was getting irregular scratches at the edge. The tip and heel were being ground more than in the middle. When I worked thorough the progression and shaved I found the edge was pretty irregular, some good spots, some not so good. Shave-able, but not what the razor is capable of doing.
So is my technique bad?
Do the Dovos come from the factory with irregular grinds and I just need to take the time to work a new bevel all the way across the edge?
Can I feel for burr formation to determine when I reach the edge, or is that no good on a straight razor?
Here is my progression:
King Ice Bear 1200, 4k, 6k
Naniwa Superstone 8k
Balsa strop with 1 micron diamond spray
Rough side leather strop
Stones were leveled with a DMT extra-coarse plate
I use just enough down pressure to maintain even contact across the edge. I place the index finger of the right hand on the convex edge toward the spine, with a loose grip on the scales, and two fingers on my left over the convex at the toe again toward the spine. I use the water beading in front of the edge to ensure even contact.
Thanks for any thoughts. I can shave with what I have...but I wouldn't be using a straight razor if I left well-enough alone:)

I just hold the shank when honing razors. You really shouldn't need to touch the blade at all.

Pass on burr formation as a technique for doing razors. Also you will need a consistent geometry - no smiles or frowns and no irregularities. Then you can go with refinement.
A 1 micron diamond spray finish will be harsh. Diamond at this level of refinement isn't 'comfortable' so you should consider a finer edge and CBN or Chromium oxide. Diamond begins to be more comfortable at finer grits in the range of tenth micron or finer.
