No. Gugi's post was meant for this thread. Double Arrows are notorious for having issues such as what he mentioned. I think he just misunderstood and thought you got the DA for $15. It would be best for you to send the razor out to get honed. Like someone mentioned earlier, Utopian was offering one free honing per person and the feedback has been good from what I've read. Shoot him a pm and see if he's still doing that. As far as the antique store razor, I say go for it. Almost all vintage blades are worth the antique store prices. Just make sure you aren't getting a damaged blade.
Good luck in finding someone to hone your razor for you.
