So, the idea is that this is a good razor to practice honing on? I mean the advantage to picking one on ebay is that this has no warped blade or uneven edge, am I right?
I am not sure if this will end up being something useful, but there's only one way to find out.

My personal opinion is that the most useful thing for people learning to hone is to have a razor with just a bevel set at the 1k level. The main challenge seems to be to get this stage correct.
