This happens sometimes to a TSUBA :

Daniel, it seems to be a BIZEN OSAFUNE smith, probably YASUTSUGU as Kyle says. For better results, clean the NAKAGO (tang) carefully with your wife's toothbrush and care to have the light from the side when making photos

.....That looks like an authority. That looks like a pricelist. Not impressive.

As Luis said.

Yves, as far as the photos allow a judgement, I would put your TSUBA in the 50 - 100 € range as it actually is. If it were in good original condition, I believe it would be about double of that, so not really a treasure! With some careful work and soft restoration to stop the corrosion (bone, ivory, antler only!) it could still find its place on a IAITO. Do not count the working hours!

Stephen, my first impression was MITSU, but you are probably right. A very 'individual' TOMO? Let's see what the masters of the writing brush say!

Marco, possibly BISHU KUNI no JU OSAFUNE HIKOBEI SUKESADA, but the photos are not very good. Please compare https://www.aoijapan.com/katana-bishu-kuni-ju-osafune-hikobei-sukesada

Bill, you can show the blade in full and in details here so we have a good impression of what it might be. The signature should be compared with those of confirmed originals, and if the condition allows, you could present the blade to a SHINSA panel. If the signature is genuine (which is not automatically so) and the blade in good shape (please refrain from all DIY cleaning or polishing attempts!), you could possibly have a very valuable blade.

Stephen, if the package is indeed 15 lbs., then it's largely enough for a TANTO. You can calculate 4 - 5 times the weight of a blade. But the problem is that these nails are only wrought iron, so you would need either to carbonize them to make the steel quenchable to hardness, or you will have to add some high carbon steel to form a cutting edge (WARI-HA KITAE). You could use an old file for that. Many TANTO were made in KOBUSE, MUKU or MARU construction, so you would need a lot more high carbon steel than (soft) wrought iron for a blade. The whole forging process for a TANTO is not really difficult but you need some experience to get good results. ------------------------- Just adding as I see that the package is less than a pound: Probably enough for a TANTO in KOBUSE KITAE if you use the nails as SHINGANE and add high-carbon steel to form the KAWAGANE.

Chris, nice project and obviously good craftsmanship! Congratulations!

Yes, I am impressed, and yes, I know who SUISHINSHI MASAHIDE was. Maybe I have to correct what I thought TOSHO TSUBA are (which I collect).

David, your TSUBA is simple and very nice, and it is probably made by a swordsmith, but I would hesitate to call it TOSHO. Compared with other TSUBA which we tend to put into the TOSHO frame, it is a different style. No criticism from my side intended.

Yes. You called it a simple TOSHO TSUBA, but please compare.

Peter, with a small hammer and without heat. By the way, I cannot see TOSHO style elements in this TSUBA.

YASUKUNI?

Matthew, in the contrary! Any DIY attempt to improve the condition of blade and fittings may damage them! A very thin layer of oil (not dripping of course! You don't want any oil in the sheath!) as recommended by Geraint is good enough for now. The age is not of much importance for the value. For us, a 500 year old blade may be called a relatively new sword (SHIN TO). The quality shows when the blade is polished, but this has to be done by a skilled and trained polisher.

Cnovak01, please sign all posts at least with a first name plus an initial so we may address you politely. The photos are not well focused so it is difficult to see details. The photo of the NAKAGO (tang) is upside down. The signature seems to read BISHU no JU TADAYOSHI.

Chris, could you please show some photos so we know what you mean?

How thick is that TSUBA? It is probably not made in the classical KO-TOSHO style, but elements of these have been used much later in EDO JIDAI. The surface looks indeed a bit like HIGO or some JINGO TSUBA.

Marco, very nice work, but how do you pull the boxes out?

It is not rare to see TSUBA that have been repurposed in later times for decorative reasons. I have one that has probably served as lock-plate for a door.

If I may add a small detail: Date is KYOHO JU NEN HACHI GATSU HI (a day in the eighth month of the tenth year of KYOHO). This is often a more symbolic month date, as February and August were thought to be good for quenching a sword blade. I read that in these month the water temperature was especially good for that, but as the smith had to warm the quenching water to a suitable temperature, this is probably just a mythical thing.

Stephen, that was really a nice one, but now. heavily corroded. I wouldn't be too sad you didn't catch it!.

Thank you, I see it now!
