  1. Bruce, looks like a '98 with blackened fittings that shows sign of age.
  2. Thought I would put up a (OTA) YASUTSUGU, he is featured on page 194 in Slough. Although rated a Medium-High Grade Gendaito, he did make some really nice swords. The nice polish on this example, displays his skill in sword making.
  3. WOW, thanks JP! I wonder if someone did polished photo micrographs of the grain structure?
  4. There is no doubt that early Mantetsu swords exhibit HADA, fine grained it may be, but definitely there. I have some. Some of them even had wavy HAMON. The steel used in a Mantetsu sword was made in an electric furnace, not the traditional TATARA. An electric furnace is just another way of providing heat to the raw materials. As you all know, the iron/steel used in a sword made from TAMAHAGANE never melts, it is made into a sponge, full of impurities, and gases. Repeated heating, hammering and folding remove the un-wanted impurities. So one could assume that at least in the early production of Mantetsu, the metallurgists were trying to reproduce a TAMAHAGANE like material, or steel sponge in the electric furnace. Using the high-speed power machine tools of the time, this sponge could be quickly turned into a many times folded homogeneous piece of steel. This folded hot steel could then be hot sheared, and the center pierced into "hockey puck" like pieces or donuts. So, it is commonly assumed that the softer iron core was inserted into the outer skin steel, some liken it to a rod inserted into a pipe. The longer the pipe the greater the probability of voids and discontinuities exist on forge welding, so a shorter "pipe and rod" system would guarantee no forging faults. In the sword forging process, this billet would be drawn out and lengthened by repeated heating and hammering into the sword shape. It is feasible that the Mantetsu steel pucks were made in Manchuria and distributed to sword makers in many localities, like boxes of donuts, but with a core of soft iron. Getting some Mantetsu swords, cutting and sectioning them would confirm their production methodology. So in summary, you have to assume that the above method would lend itself to mass production, ease of production, and a consistent product. The very rough sketch below is an attempt to show how a shorter pipe and core would have many production, manufacturing and quality benefits over a long thin difficult to make pipe.
  5. Glad you asked Rob, the photos you asked for actually show how nice the sword really is, with the patina expected on a combat sword.
  6. I offer for sale a NAGAMITSU gendai-to. No stamps no date, in fantastic RS (type 3, type 0) mounts, complete, even down to the original securing screw. NAGAMITSU is becoming (or has in fact become) a really desirable collectable sword smith of WW2. Much has been written about him, and I welcome you to research him. The value of this smith is increasing, and will continue to increase. Many of his swords are mounted this way, with lacquered ITO over a burlap SAME, these are premium mounts. The beautifully cut MEI, is on a a very clean NAKAGO. Also, like many fittings of this kind, there is the "broken heart" stamp on the SEPPA. There is no rust, no pits, in war time polish, with two small nail catchers (in photo) that attest to its war time use. This must have belonged to a wealthy officer as it is a premium sword. At only AUD2550, express delivered anywhere, that is less than USD 2000 at todays exchange rate! I doubt you will find better value for money.
  7. No idea, but I like it!
  8. Here is a (Kajiwara) HIROMITSU. It is dated December 1943. It looks like it started its life as a special order Civilian mounted sword, and later, taken to war in a leather combat saya. It has no stamps. The fittings are a complete set of rare Showa Period pine tree motif in brass, and a blue/green ito wrap often seen on WW2 swords. The blade is in full polish. This famous smith was from Fukuoka, was responsible for some nice traditionally made swords.
  9. You probably would guess that in my collection of Mantetsu swords, I would have a piece that may settle the controversy. I have what I think is one of the earliest examples made, a Winter 1938, when production commenced, (or end of 1938 as the records show). And as most of you know, I have an example of every year including 1945. This sword has a DEFINITE hada, fine it maybe, but very visible. My photography is poor, but there is enough hada to show it exists.
  10. I bought all this equipment to polish old blades, now you tell me it's not appropriate? You sure know how to rain on a guys parade! (This should get me kicked off the forum for a while!).
  11. Markus, thankyou for your reply. I realize the enormity of task at hand. However with books by Kishida on Yasukuni, and Wallinga on Minatogawa, Slough on hundreds of Gendai smiths and the latest works of Malcolm Cox, a book covering those missing from these publications would be a great start. Most of us have these books already, or access to them. You could also put out a call for any missing oshigata that we could could supply from our collections. Hope this helps, and I am sure that the enormous burden you have undertaken could be somewhat relieved.
