Welcome to SRP. Going by your post count I assume you are new to the forum ? If you've been around long enough to have the Dovo and the 4/8 perhaps you've seen the SRP Wiki honing guide here. You'll find a lot of info and videos in there to start you in the right direction.

Obviously you bought the hone because you want to maintain your own razors. With that in mind I would suggest that if you have an ebay or flea market special or two practice on those. Maybe send your Dovo out to be professionally honed ....particularly if it is your main shaver.

This will give you something to shave with and to compare to your efforts on the other razors you are honing. That is how I went about it and it worked well for me.
