Just thought I'd add a couple of points: First, "too many strokes" is relative. If the razor is already shaving and just needs a touch up, sure, a few strokes will usually bring it back around. But if you're working on a razor that you haven't honed previously, you'll probably get very, very old this way before you have a successful shave test. The important thing, as heavyduty says, is doing the "right number" of strokes. Sometimes that's a lot, sometimes it's just a few.

Also, the size of the honing bevel is mostly dependent on the razor's grind, not the number of strokes used. With a full hollow, you can hone away half the blade and the bevel size probably won't change much. On a wedge or other heavy grind, the bevel is going to increase naturally as you hone it. Sometimes on heavy-ground razors it's necessary to hone away a lot of metal to get to a clean, sharp edge, and in these cases you will end up with a wide bevel.

Just a couple of thoughts,
Josh
