I think it may be beneficial to both buyer and seller. One reason I like the idea is that if it is incorporated it gives the seller of shave ready razors some credibility if a buyer starts dragging his name through the mud. Say a buyer is unhappy with a razor sold as shave ready and makes contact with the seller, that is fine. The seller can make it right or give a refund.

I have seen new shavers post on SRP about the poorly honed razor they received from noted honemiesters. While it could be the honing it is more likely the lack of technique or improper stropping..... or both. For established honemiesters this isn't a problem. Their reputation precedes them. For the newer members venturing into the honing for hire it could be an issue. "Don't buy from that guy, I heard he doesn't know what he is doing."

OTOH, a demonstration of honing ability by the seller will give the new guy some assurance that the claim the seller is making that he has the skills to hone a razor to shave ready is a valid one. If an unhappy buyer takes a gripe to the public forum the seller can at least say that he has passed muster with the selected judges of his honing ability.

BTW, I have no ax to grind. I have no plans to sell razors on the forum shave ready or otherwise. If I buy a razor from any source if I don't like the way it shaves I hone it until I do. I just happen to think it isn't a bad idea.
