One of the first razors I bought was a 7/8 TI from an ebay seller in Germany. A well known, well regarded seller based on his feedback, and comments on shaving forums. So I get the razor and it has a double bevel on one side. A new razor. Anyway, I worked my tail off correcting that bevel, and when I was finally done it became a favorite. A darn good razor with darn good steel. Pre-C135 steel.

I still contend, based on my experience, that obscure vintage razors, well known vintage razors by and large have good steel. So if sloppy QC, or poor honing by whoever owned it along the way, make for a bad bevel/spine, it can either be corrected, or it is too far gone. One way or the other, the shave is what I judge the razor by. The honing is an incidental process that I, or someone else does, to facilitate the end purpose. The shave is the thing that makes my bell ring.
