  1. British Hi Fi systems, (they sound better), and old vinyl records, (analog recordings if possible).
  2. Human hands sarute left, ape hand sarute right.
  3. That's pretty true Hamfish, thats why I started the high class Gendai thread.
  4. KABOKU. George Trotter's comment above in 2015, prompted me to put a few pics up of the sword that he commented won the 2011 Sydney Shinsa. I am "the lucky owner" as George describes. The sword is as interesting as is the historical story above, documenting on the killing of his assassin with a severed hand. This sword is in wonderful polish, and any marks seen in the photos are due to cleaning the oil off.
  5. Today, when the latest technology comes out, every one breaks their necks trying to adopt it, ie look at the ques for the latest iPhone, thinking it is better and they must have it. So why wouldn't the same apply in the 1940's when a new technology in steel came out, that some sword smiths rushed to try it, and may even have found the properties better? Even advertising the fact when they cut the mei on the sword?
  6. Without seeing the result in the hand from the rotary kiln, if it is described as sponge iron, it should be be similar to tamahagane in properties.
  7. From my collection of WW2 period tsuba, I have decided to let a few treasured pieces go. The express/tracking/postage cost of AUD60 will need to be added, but this is generally the safest and quickest way to get them to you. So add the AUD60 to the price listed..... 1. The EXTREMELY rare Sakura Showa tsuba, AUD200. NOW SOLD!!! 2. A complete Tachi set including ALL the Seppa, AUD120. 3. A '98 Tsuba with the cut out that suits the outfit that came with a leather securing strap. Normally on outfits with an old blade, AUD120. 4. A '98 Tsuba that is used on a outfit with the "chuso" spring clip, AUD120. If two or more are purchased, only one AUD60 needs to be added. These are good, collectable, useable, as found pieces, no cleaning or chemicals have been used in my time as owner. When converted to USD or EURO, they are well below current market value.
  8. When a sword is made from tamahagne or sponge iron, it is formed into a sword by hammering, folding and forge welding, the iron never melts. The swordsmith controls the carbon content during forging. The forging process removes all the contained gas and slags from the sponge, and the hada you see in a sword is the layers or folds that result from forge welding. So this sponge iron becomes steel (Iron + Carbon). So to answer your question, Sadakatsu made steel from tamahagane or sponge iron ONLY in the traditional forging process, not by a steel separate making process. As I said, the steel in sword making the traditional way has never been melted. For my sins, I am a metallurgist.
  9. Valuations from photos can never be reliable. Estimates can be given based on sale prices of similar swords, in similar condition and in different locations. But then you are basically valuing the sword smith without having a close look at his work. Not saying this sword has any problems, but how do you tell from a photo if a sword has had an a back yard polish and irreparably damaged the geometry. Or other fatal problems. One thing I have learned from collecting, it is about the blade, not the signature. So if a valuation is asked or given, it must be with certain conditions, and a "range" of values to account for the actual properties of the individual sword. So in a case like this, it could be from USD1000 if the bade is stuffed, to USD3500 if the bade geometry if original, shows potential (hada, hamon, hataraki), but at the end of the day, a sword is worth what someone wants to pay.
  10. Gassan Sadakatsu died in 1943, and there is some debate as to when his son started making his swords, as his father became ill/infirm. These swords still paper paper regardless. Bryce, I don't think the term Western Steel can be attributed to what you have researched. Firstly, it was not made in the "west" and secondly, it was still made from Japanese iron sand. Western steel normally applies to rail tracks made in Europe etc. And as you correctly point out, the steel made in the rotary furnace was still a sponge (like tamahagane) and not a melted refined steel. And metallurgically, if it was not inscribed on the sword, there is NO WAY of determining what metal it was made from. It is interesting you say that the Iron Sand Company was established in 1937. When I was searching the world for my Sadakatsu, a number of collectors said "try and find a pre 1937" , coincidence, I don't know. I found a 1933. I have swords by other smiths that indicate different steels being used in their manufacture, and maybe these new technologies were being shown off as advanced technologies back then, and maybe even superior quality. Regardless, they all paper, and are accepted as true nihonto. And to inscribe the steel companies name on the sword, Sadakatsu must have thought highly of the steel, OR made them for the Steel company as promotional swords of the time.
  11. You can PM me with a photo, length of saya, width and thickness, I may have a spare somewhere.
  12. Jacques, Jacques, Jacques .... The RJT smiths as part of their approval process were issued the scarce tamahagane, and red pine charcoal to ensure their blades conformed to traditionally made Nihonto. The star was added by an inspector, after approval, and raw materials accounted for. Some RJT smiths made swords to special order, that don't have star stamps.
  13. I've had a few messages puzzled why this hasn't sold, considering it includes postage anywhere! Someone suggested I take better photos, well here they are. And another asked if it has ever been in a fire, WELL NO! It rings like a bell. And Brian will get a donation to his get well soon. Boy, must be a tough market out there!
