LOL.

Well, looks like you bought the lower grit hones. Honestly though, its probably cheaper and less frustrating to send the blade to a honing machine (honemeister). You really don't need anything other than a finishing stone to keep any razor in perfect shape. Once my razors are honed, I never drop below 12k.

As for time, it depends on how sharp you want your razor to be and how good your maintenance is. I suppose its possible to go a full year without needing to touch up on a 12k. But I'd touch it up every time you feel a difference in the shave.
