G'day Guys, Thanks for the help. Good to know about the dodgy copies. Yes it is for a katana. Here are some of the other fittings. Cheers, Bryce

G'day Guys, I have a set of koshirae which has fittings that feature a dragon in clouds. The only problem is that the tsuba doesn't match. I think the tsuba may have been swapped out some time in the past. None of the fittings are signed. A Google search produced this image of a tsuba that appears to be a very close match to the rest of the fittings. Can anyone tell me anything about it, or even better where I might find one like this? Cheers, Bryce

G'day Thomas, I can see what you are getting at with the example you posted. I am not sure this applies to all of the examples listed. Perhaps the masame is so fine that you can only differentiate the layers when you look really closely? Here is a photo of two examples by Gassan Sadakatsu. From a distance they both appear to be koitame. When you zoom in you can see the masame. Cheers, Bryce

G'day Thomas, You have lost me. Can you please explain this a bit more? Cheers, Bryce

G'day Alexi, I am no expert, but my favourite smith is Gassan Sadakatsu who produced many works in masame. I think consistency, plenty of jinie and no kitae ware are what I like. The hada can be very tight with little differentiation between layers or more vivid. Both types of hada can showcase the smith's talent. Below is a link to a thread where I show some examples of this. I must admit to still being baffled sometimes by what makes a blade extraordinary compared to just excellent. Perhaps some of the more experienced members may be able to add more insight. Cheers, Bryce

G'day Guys, A British sword maker by the name of Henry Osborn tried to revive the "falchion style" point in his cavalry swords of the late 1700's early 1800's, but his idea never really caught on. Here are some examples of his work. Cheers, Bryce

Here is a link to another tanto like yours. Tanto : Gassan Sadakatsu – 日本刀販売の葵美術 (sword-auction.com) Cheers, Bryce

G'day Kyle, Further to what Ray has already told you, your tanto was made by Gassan Sadakatsu, in 1929, to commemorate the birth of the crown princess (Taka Kazuko). Gassan Sadakatsu was one of the best Japanese swordsmiths of his time and made many commemorative pieces like this. Tanto like this, were not made for military use, but have more of a spiritual significance. Potentially your tanto is quite valuable, but unfortunately it looks like it has had a very hard life and this may effect the value. First thing to do though is give it a very light oiling to prevent any further oxidation. Don't try to remove any rust yourself as this will damage the blade. Gassan Sadakatsu is my favourite smith and I agree with Ray that your tanto is genuine. If you do a search on this forum you will find plenty of information about him. It looks like you may have lost the wooden handle of the shirasaya and also the habaki (metal collar) that would have gone on the junction of the blade and nakago (tang). Here is a picture of mine to show you what I mean. Cheers, Bryce

We have seen this blade before. Cheers, Bryce

G'day Andrew, Your blade looks very promising. Are you able to post a shot of the boshi like this? Unfortunately older NBTHK papers like yours are no longer viewed as being reliable. That doesn't automatically mean the attribution is wrong though. Cheers, Bryce

G'day Peter, I am interested in the evolution of the "Gassan habaki". The earliest ones I have seen to date appear to have been made by Sadakatsu. Do you know when yours was made? Cheers, Bryce

G'day Guys, Gassan Sadakatsu is also famous for his take on Yamato Hosho. Here is an example made in 1940. Cheers, Bryce

G'day Matt, Gassan Sadakazu and Gassan Sadakatsu also made some of these. Here is one by Sadakazu. Cheers, Bryce

RIP Roger. We shared many interests and had some great conversations. Bryce

G'day John, Heck of a sori on that thing!! Cheers, Bryce

G'day Guys, No one has posted on this thread for a long time, so I thought I would add my boxed Gassan Sadakatsu, with nice type 94 koshirae. Cheers, Bryce

Thanks Paul, I appreciate you taking the time to explain it to me. Cheers, Bryce

G'day Paul, You and others on this forum in the past have mentioned blades having a bad shape. I assume this refers to aesthetics and has nothing to do with the practical performance of the blade. As you have said you like early koto blades does this mean you prefer the blade shapes that were common in this time period? What is a bad shape and what is a good shape? I am not trying to take the piss or anything, but am simply trying to learn. One thing I do know is that what we like is very subjective and changes over time. Below are three examples of Gassan Sadakatsu's blades. How would you describe the shapes of these blades, good, bad or indifferent? I like all three. Cheers, Bryce

G'day Sam, Tsuruta san of AOIJapan described this one as kaen. Cheers, Bryce

The hada on the 1938 example (top) is very similar to this 1943 example (bottom) with ayasugi. I guess the smithing process is identical up to the point where the layers are mechanically manipulated into the wave pattern. Cheers, Bryce

G'day Guys, Below are two different examples of Gassan Sadakatsu's masame hada. The top blade is dated 1940 and has very tight masame hada, with little contrast between layers. The bottom blade is dated 1938 and has high contrast between layers. I believe he achieved this contrast by combining different steels in alternating layers. This is the type of contrast you usually see in his ayasugi examples. I assume he used a single type of steel in the top blade. Cheers, Bryce

Come on Nobody, you have to give us some better photos than that. Cheers, Bryce

G'day Guys, Here is a shot of the boshi. Cheers, Bryce

Wow. This seems to confirm all the stories about military swords being destroyed upon their return to Japan in the past. Cheers, Bryce

G'day Guys, One of my favourite blades, an early Gassan Sadakatsu made in 1921 when he was still in his Bizen den phase. It has a nagasa of 68.4 cm and koshi sori of 1.7cm. Cheers, Bryce
