And they take quite a bit of work to get them honed properly. It may have been purchased "shave ready", which would be fine. But if it is straight from the factory it will need work.
I've got one, and it shaves nice enough....after a few hours of honing. They're definitely not reliably shave ready from the factory, and mine had a lumpy spine that I needed to straighten before it would take a good bevel. It's not just a razor, it's a hobby...
I have one honed by Buca and it shaves great though it is bloody heavy! I have 7 of the older 'Double Arrow' razors with the white scales which I honed myself but boy...that was a lot of work! Still, fun to shave with. Welcome to the forum, by the way!
Gds are great shavers. I dont find the process of honing one to be a problem. 2 minutes on a chosera 600 and thebevel is set. Although some batches are easier than others.
Some GDs are works of art, once customised. Lovely razors. I have read many reports of bad ones, but the only one I got new was easy to hone, though it claimed to be shave ready. I have a few custom ones and they are all great.
