I have some pretty old razors, incidentally they seem unused and show no hone wear.

However, I found them hard to sharpen, with and without tape.

Then I calculated their bevel angles and all were above 20 degrees.
They're heavier grinds.

If the angle is too low, simple, add layers of tape, but too high?
Maybe it was more common to use those angles in the day.

Do I just keep honing them on the 1K until I make good contact over the entire edge? Without tape that is, so things wear down?

I'm fairly sure I honed such razors in the past without tape and things eventually worked out.

Tape isn't working on them and the angles will only get higher, so just checking in to ask how you go about honing those razors?

I figure it's just a matter of spending time on the 1K
