Doom sayer Keith? (or would "doom saya" be more appropriate?). I don't think you're a doom sayer at all. The fact is, whether or not it's a koshirae of no consequence doesn't change the fact that it has fallen into good hands. Someone who will enjoy and look after it.
I think sometimes we can be too purist about our passion.
I have about 20 or so swords, most of them of no consequence. The majority have come from combing antique shops in Asia and occasionally the UK. I have uncovered a very nice Kanbun shinto katana in original mounts, a fantastic find from Sumatra in military mounts, which may well be a Kanemitsu (yes that Kanemitsu).
And one or two others of interest. This doesn't negate the fact that some of the other swords I own, I find very appealing too.
If I hadn't found them who knows what would have happened to them? And it would be a shame if they rusted away and end up discarded to land fill!
Doom sayer? No sir, not in the least. My friend who owns this is very pleased with the comments from everyone here, and is that more knowledgeable as a result.
He thanks you all, as i do, this site provides a huge service to the preservation of Nihonto and that's a good thing. An exceptionally good thing.
