You have a few options for maintenance of the blade.
You can get a barber hone, 12k Super stone , or 4/8k Norton.

I think the most versatile of the three will be the 4/8k combo, you can shave nicely off the 8k, and if you add a CrO strop to the set up you will be in great shape. On the other hand if you need more than a touch up on the razor you can always use the 4k side then go back to the 8k.
