Apologies to my fellow board members. Date-dono expended his eloquence allowance yesterday. I kind of get the feeling he likes my current avatar.  (Go to www.wodefordhall.com/makiwarapoetry.com and scroll down to the bottom to see what happened.) Saionji |

Well I would, but I am not sure at this time who made it. The mei, that WAS on both sides of the nakago, were ground off by the vet. that brought this yari back to the US. I'm not sure why he did that. It may be that he was hiding something.
I have asked around about trying to recover the mei. AS you can still make out the outline of many of the kanji. I am checking with some CSI guys. There must be some kind of weak acid, or something that will bring up these areas. If any one here has any ideas, please tell.
I got it back from the base polisher last week. Still a long way to go, but it is going to look great. Likely, about 6 mo. of work to do. These yari are SOOOOO hard to polish. Most pro. Japanese polishers will not even take them on.
I'm still recovering from gulf wars. I hope to get started on it next few days.

The mei...were ground off by the vet...I'm not sure why he did that. It has been a longstanding U.S. tradition to remove arsenal marks and army proof stamps from captured military arms. I don't recall how this started but it appears as habit from the spanish american war onwards. When servicemen shipped their belongings home weapons had to be inspected, some inspectors were overzealous and ground off every conceivable marking they could find. (a frequent occurance with weapons bearing non-english standard letters) Others inspectors were much more friendly just nicking off a piece of a proof/acceptance mark so while obviously "de-militerized" it was still identifiable as to which arsenal. Another possibility is that you piece was a forgery and had it's mei ground off by a polisher. Though this would be unusual, the destruction of mei that have been identified as false is more frequently a post 1949 occurance, most commonly instead of being ground away, they are simply hammered over to osbscure the mei. As an interestign side-note there is a movement to stop this practice as well, instead marking false signatures with a couple of well placed centerpunch marks. This method disturbs the least amount of patina, and does not obscure the signature which may have importance later. If the mei was ground off (like with a grinder) and coarse, there is probably little patina left to wory about, so a weak acid (dilute PC board etchant works) would be fine. If you realy want to get somethign to pop out you could always go with magnafluxing it. Gaurenteed to make any ground and polished serial number pop out. -Takeda |

Oh I'm sure it wasn't a false signiture. That would be very rare on a yari. It could be as simple as your arsenal mark removel. No telling. There was a long mei on both sides. And yes, it looks like some kind of grinder was used. And yes, there is no patina to worry about. 'Magnafluxing'  Could this damage the blade in any way? I would realy love to recover this mei. I have seen a bunch of Jumonji yari, and this is one of the best. I have a feeling it was made by someone very good. |

'Magnafluxing' Could this damage the blade in any way? I would realy love to recover this mei. I have seen a bunch of Jumonji yari, and this is one of the best. I have a feeling it was made by someone very good. Magnaflux is a trade name for a flourecent chemical that one applies to metal crafts to check for hidden and microfractures. It is used as a critical components check on pieces that cannot be damaged by other forms of testing. There are also some other non-florecent versions that can be seen in plain light that operate on a similar principal, but are much less accurate for testing. (but work for the serial number trick, and IMHO a bit better than the acid etch) I have not seen any problems and they should be less invasive than even a weak acid. (Then again I never tried them on a japanese sword) Another point to consider is actualy polishing the tang with the either binsui or keisei stones, applying hot vinegar a few times and waiting 30 minutes. The nature of japanese sword polishing opens up the grain of the steel, applying a warm/hot acid (even a very weak one) at this point should make those marks stand out like a sore thumb. After all the increased desnisty where the marks have been chisled in is functionally no different than the hamon for the chemical reaction. (Sorry I did not think of that before) -Takeda |

Soon Brother. It's all H stone grey right now. I've never seen such a nice hamon on a Jumonji before though. You going to S Joust? I will bring it, and you can see it in person. T
