Thankfully I haven't caught RAD yet.
I only have my original Dovo En Vogue that I honed myself.
And a Wapienica that I bought "shave-ready" to compare my honing to that of an experienced person.
And two of those cheap Double Arrows off ebay to experiment with.
There is a nice vintage Henckels I have my eye on but I've resisted so far.

Yes, I'm sure glad I don't have RAD.
