Not a lot to add, in fact I find my thoughts esentially mirroring Jims. I do think that if this were a definate Muramasa, then eBay would be the last place to sell it.
I have no data on the current market value of a genuine tanto blade of this maker, but I would have thought significantly more than 5k?
Anything like this should be in a specialist auction where the auction house can add its 'weight' to the validity of the piece, and buyers or their agents can handle the thing in person.
I wonder if the seller had it appraised and the best opinion offered was that its probobly a 17thC forgery.
That said, it looks a nice blade, and the price is certainly a goodly wad of cash! I'd be interested to know where its path leads now.
Well, assuming its new owner can resist the urge to go on a killing spree or do himself in with it
