JAL Posted May 14 Report Posted May 14 Dear all, a signed nidai Kashu Kanewaka (Matatsuke) wakizashi (Hozon) has this structure in the ji hada. Not looking like an umegane. Any ideas? best regards John L. 1 Quote
Katsujinken Posted May 14 Report Posted May 14 Definitely looks like a repair of some kind. That is not natural. 3 Quote
Ray Singer Posted May 14 Report Posted May 14 Unfortunately this looks very much like a welded "umegane" (a modern repair to fill a flaw in the blade). We've discussed the same type of feature here previously in another sword that was sold online. 4 Quote
JAL Posted May 14 Author Report Posted May 14 Looked artificial to me as well, but seemed melted droplets of metal and then polished. Most umegane I have seen were flat one color. Quote
Ray Singer Posted May 14 Report Posted May 14 I use the term "umegane" here loosely. It really should only refer to metal inlaid into the blade as part of the repair process. In this case it appears that welding has been used to fill a void or flaw in the ji. The last place that I recall seeing this was an Enju daito, with a repair having the same appearance. Quote
ROKUJURO Posted May 14 Report Posted May 14 Looks like micro-welding to fill a FUKURE. Technically better and more durable than traditional UMEGANE, but the process uses high heat that will inevitably be introduced into the steel. If carefully executed, the affected area might remain small. 1 Quote
JAL Posted May 14 Author Report Posted May 14 Thanks all, Hozon papers are from end 2022 and I think it got papered with this repair. best regards John L Quote
