Yeah, RAD does strike us all. I was ADAMANT I'd only need at tops three razors, but I HAVE been able to stop at 7. I've bought more but given some away or swapped them.

In regards to 'never' needing a bevel set (unless damaged), that's possibly not quite 100% correct. A razor's edge, I believe, will only take SO much refreshing before it'll degrade and will need to be taken back on a harsher hone. However, depending on how many razors you end up with (i.e. rotating between them) this could be several years.

I'm no honing expert but I'm pretty sure this is pretty well correct.

BTW, in regards to collecting razors, it's well worth mixing up styles. I really think one needs at least one of each of these:

A full hollow
A frameback
A wedge
A W&B (if not one of the above)
A French razor (because they're so cool, I am yet to find mine)
A Swedish razor (if not one of the above because the steel is amazing)
A kamisori (I'm yet to find mine)

Here are the razors I currently have. I use all of them regularly.
