The biggest problem that I have seen with wedge razors is that the spine wear in most cases is more than off. Typically, there is uneven flattening along the spine and bevel and typically the wear pattern is not the same on both sides. These normally take a significant amount of time to hone and various techniques from 45 degree angles, to rolling X to removal of a lot of metal, to which of my hones will work the best, to how creative can you be to get it to shave. The good news is that they normally are nice shavers once you get them there.

Have fun,
