I have a both new and a vintage TI with straight blades. I consider myself lucky.
I wonder if this is a typical example of the warped blades on some TIs.

Both sides honed (partially, lots of work to do yet) on a diamond plate. On one side, the middle of the bevel is the highest point; on the other, the toe and heel are.
This razor was bought new 30 years ago and has been kept in its box until a little over a year ago.
One of the best ways to hone that type of razor is on a very narrow hone. If you have a hone that is 3/4" thick or greater, stand the hone on its side and hone that way. That will make it easier to apply greater pressure to those areas that need it most. If you try honing the razor on a wider diamond hone, you may remove so much material that you grind though hardest part of the steel. A warped blade is difficult to hone, but it will still shave. It is not necessary to get it perfectly straight; that might be impossible.
Thanks for that. Great information. It goes against my inclination to make perfect flat bevels on all of my razors, but I can see that I might have to compromise on that from time to time.
You mention grinding through the hardest part of the steel. Are TI razors differentially hardened?
When steel is heated to high temperatures and then cooled, the parts closer to the edge are thinner and will cool more quickly than the thicker spine. Thus, all straight razors have a difference in hardening.
Agreed. As far as I’m concerned it’s case closed on this razor. I have half a mind to send it back to Germany at my cost but what’s the point? Just because someone magically gets an edge on it with some fancy honing technique does not mean that it will be usable or easily maintainable for me on an ongoing basis.@Tomo, this is very disappointing (so far). I would not have thought that such a warped blade would be within the acceptable range for Aust. It really makes me re-evaluate my opinions. I don't want to do that, because I too have a really excellent Aust razor, with the cheapest scales.
