I had a blade where a tiny hagiri popped up after polish. 27 3/4” nagasa, really nice activity all through out. I liked it so I kept it. It was Teruhiro/Teruhide whatever that line of Shinto smiths was, but this was definitely a shin Shinto piece if genuine signature.
Luis, I don’t recall ever having a blade signed Sa. I know a friend of mine did that he sold at SOS almost a decade ago. If it was me, for the future I always allow for an inspection period regardless of selling it on eBay or elsewhere.
On returns, I don’t mind. I’m fortunate that I don’t need the money, this isn’t how I feed my family. Also, I know on these types of things you just need to see them in hand to be sure, and it’s not like they’re buying some $20 gadget of Amazon.
i recently sent 3 blades to be polished and a 4th to get an opinion on whether or not worth the restoration that I just had a feeling something was special about it. I got a call when the swords arrived and was asked why I wasn’t polishing the one I sent for him to check out as it looked Rai, so off it went. Had another friend tell me the hamon looked like Rai kunitoshi to him as well. So fingers crossed, we’ll see how it turns out. One of the others was a mumei blade, almost 28” nagasa. One of my friends studied it in hand and was thinking Sekishu Naotsuna. The person that handles the polishing thought it was Shinto. So that one is a total gamble, but it had nice activity so will probably enjoy It anyways. Added some pics.
