Hi, I just bought a Ryujin katana, the hamon is a little close to the edge at one point, and that point has a little ding in the edge straight out of the box today. Is this a cause for concern? This is my first post and my first katana, I don't know much . (Returned now, thanks for the replies!).

Honestly, I'd be a bit concerned with it if I plan to cut with some amount of regularity. By nature, the edge will always lose a bit of material when you sharpen it, and a cutter should be sharpened every so often to maintain the bite. That said, I'm sure this would still be perfectly serviceable as a light cutter - stick to small water bottles for this, and get another sword for the bigger, tougher targets (maybe a through-hardened piece might serve you better, or a differentially-hardened katana from a more reputable manufacturer).

Yikes, that is concerningly close to the edge. In one shot it looks like the hamon almost drops off the edge, which is a serious flaw. If the hamon runs to the edge, the risk of stress fractures increases (e.g. cracks) increases. As well, when there is minimal space between the edge and the temper line that means there is less hard material to sharpen with subsequent polishing/sharpening.
For a live blade that is expected to see cutting and impact, that is not a good one to use. If the edge is indeed blemished as well (it appears so), I would just return it. Better safe than sorry.

Agree with the above two. This one is close to retirement already, and the ding just push it even more to the retirement since fixing it take away a bit of the edge too.

Thanks for the quick replies! It didn't look good, so I thought it best to ask. A Monday morning katana.

Just an update out of fairness, I got a replacement monotempered Dojo Pro #12 from Ronin, and there is nothing wrong with it. The Tsuba doesn't even rattle. The Mune is surprisingly wide, but the bo-hi seems to make up for the weight, it isn't a heavy sword at all. It can cut paper reasonably cleanly, although I haven't done much actual cutting with it. It is a fairly plain practical looking sword. So all's well that ends well.
