Ken-Hawaii Posted November 1, 2013 Report Posted November 1, 2013 http://www.ebay.com/itm/71-5cm-Antique-Japanese-sword-signed-Yasutsugu-Katana-w-Hi-caving-Koshirae-/121205436295?pt=Asian_Antiques&hash=item1c38682f87 I can't figure out what might have caused the nakago on this blade to lose a chunk of metal - any ideas?

Surfson Posted November 1, 2013 Report Posted November 1, 2013 Looks like penetrating rust to me. Tsuka may have been wet in one spot. B Quote
Dr Fox Posted November 1, 2013 Report Posted November 1, 2013 Has it 'lost' metal? Or are we seeing impact from both sides thus reducing width?? Denis Quote
kusunokimasahige Posted November 1, 2013 Report Posted November 1, 2013 Might it be an abandoned attempt at suriage ? It might be the rust thing, but the notches look very deliberate to me, and rust in general does not act in predictable ways as far as I know. KM Quote
Stephen Posted November 1, 2013 Report Posted November 1, 2013 looks like it was rusting thru and active rust was removed and left the notches Quote
Ken-Hawaii Posted November 1, 2013 Author Report Posted November 1, 2013 That makes some sense, Stephen. My first impression was that some nut with a blowtorch tried to melt it.... Ken Quote
Ed Posted November 1, 2013 Report Posted November 1, 2013 I agree with Stephen, looks like active rust was removed leaving the notches. I have seen many pieces of steel dug up, they do not necessarily deteriorate evenly throughout. Some spots will be worse than others even though it was a buried. I do hope no one thinks they are going to snag a legitimate Yasatsugu here. The mei is not right, just saying. Quote
Adrian Posted November 2, 2013 Report Posted November 2, 2013 Might it be an abandoned attempt at suriage ? It might be the rust thing, but the notches look very deliberate to me, and rust in general does not act in predictable ways as far as I know. KM +1. Look at the shape that would have been obtained, I think it's quite obvious this was a shortening attempt, abandoned for unknown reasons. Quote
Stephen Posted November 2, 2013 Report Posted November 2, 2013 I think it's quite obvious this was a shortening attempt huh? what they run out of rats to naw away with? if they were trying to shorten it why not have it done like the first one???? Quote
kusunokimasahige Posted November 2, 2013 Report Posted November 2, 2013 To add to what Stephen says, the Japanese did have chisels and saws to perform suriage. So I am not certain what happened here, but the rust story still remains elusive to me. It is absolutely useless to leave a nakago like that because suriage in this case would have been the best option. KM Quote
Lee Bray Posted November 2, 2013 Report Posted November 2, 2013 Rust is easily fixed by a layman at home. Suriage needs tools and a degree of skill. If this was an attempt at suriage, it was done by a monkey with a rock...possibly trying to keep Stephen's rats away... Quote
kusunokimasahige Posted November 2, 2013 Report Posted November 2, 2013 Not to mention the sword already had suriage : http://i.ebayimg.com/t/71-5cm-Antique-J ... .JPG?rt=nc Quote
Ed Posted November 2, 2013 Report Posted November 2, 2013 Henk-Jan, I going to say the same thing. It is already suriage. Who can predict how the rust will attack the steel ? Quote
Stephen Posted November 2, 2013 Report Posted November 2, 2013 http://www.youtube.com/watch?v=-K1hsRRUmTA why we tell newbs that active bubbling red rust needs to be stoped on Nakago Quote
Doug Posted November 4, 2013 Report Posted November 4, 2013 I'm not sure if this is the case here but it seems I read somewhere that chunks of nakago are sometimes used in doing umegane. Again, not saying this is the case here but I have seen pictures of similar nakago with deeper notches and less active looking rust. Just throwing that out there. Doug Quote
