I've been scratching my head for a few days thinking of a reason why I would need any of my other stones besides the 12k for my razor.

Beyond repairing damage is there any reason why you would ever take a razor back to say a 1k stone, resetting the bevel and working back up through the grits ?

Is there any benifit of resetting the bevel every year or so ?

I just can't see me ever letting the edge get in such a state to require any of the lower grit stones as I would imagine at that stage the shave would be very uncomfortable.

So is it just a case of refreshing the blade every so often on the 12k or am I missing a trick ?

Help me obi wan shaving komunity your my only hope
