Welcome to SRP. If that Solingen razor is as nice as you say, maybe you should get another razor to practice on. Just a thought. If you post some pictures of your hone someone may be able to tell you what it is. It would be good to know which grits you have, before starting to hone. Sounds like you're getting a nice kit together. Do you have a strop yet?

If you haven't seen the Begginners Guide you should take a look.

Good luck with your shaves and honing.
