Thanks, Mike!

I missed your answer and I am tempering now.
I reduced my soaking time to around 9 minutes and with opening my oven' door I was able to reach at 798-805C. My tempering time 2x2h, 215C. I will see.

Do I understan well I can repeat the tempering cycle anytime after the hardening?

All they want is a good handmade shave. If the honers grumble that your razors eat their stones, now then, you're making very good razors. Ha!
I am thinking about this.
