That sounds like about the average time for an edge to start to deteriorate. CrOx would be the first logical step in making your razor sharper. Lynn Abrams has a video that shows how to use CrOx or the like here: https://youtu.be/ You can buy CrOx or the diamond spray from SRD by following the "The Sharpening Center" link. You can get the .5 micron in either spray or crayon form. When keeping any blade sharp, one wants to do the least destructive thing possible to get the edge back to where it should be. Stropping on a linen/canvas, etc. strop with some CrOx on it will bring the edge back to it's original sharpness (refer to the video for details). You should be able to refresh the razor several times before you will need to be to hone the razor on a 12k stone. I think the average time between CrOx stropping would be two to three months. You probably would only need to hone the razor on a 12k about once a year.
