Is the Dovo your only razor ? I'm not saying you need a whole bunch of razors to shave with a straight but if you want to learn how to hone them it sure helps to have one pro honed and a few to practice on. The one honed by a honemiester can be your go to shaver and the one that you use to judge the others that you hone for your progress.

If you aren't an experienced honer and you are working on your only razor it is harder. You may pick it up easily or you may have to work at it a bit. I know I do. Ronnie is right about the marker test and you can set the bevel on a 4k as Randy told me if you are patient and persistent. Might be good to take Leighton up on his generous offer and get a couple of ebay Solingens to practice on.
