It depends. I've honed up quite a few of them, on average it took around 1 hour. But thing was that I knew what I was doing. For someone just started, it can actually take longer. Their edge retention seems to be okay, I shaved with one for over two months, stropping only on cotton web and plain leather between shaves, probably got around 30 shaves out of it already, and it still going strong. I would not recommend buying it though, I bought them solely for practicing purposes.Amen to what he said ^^. Honing a Gold Dollar can turn into a 3 hour (or more) task!! Its a Labor of love for the purposes of the 'honing game'! Some cannot be honed PERIOD. I believe they got the steel to hot while doing the hone on a belt and a buffer on some, and temper is ruined.Those crumble at 1k-2k and will not take a fully 'set apex' on every mm of the apex... You can't take chicken poop and make chicken soup, i could say it another way but i am trying to clean up my mouth/mannersWhenever you get a good one you can turn one into a nice shaver! I don't know how long they'll last, never done a longevity test. I assume since they're so inconsistent they would vary a lot like the difference between daylight and dark.. You will definitely get an education when honing on Gold Dollar razors, for sure!!
