Any info regarding this tanto?

[Karasunoir]

I bought this a while ago:

(tell me if the link dont work)

 

I recuired it very cheap from an estate sale, the people who used to live there were weapon collectors. The ones selling did not know anything about it. 

 

I heard some suggest it is showa era koshirae

The blade have a broken tip, its one of the reasons i got it cheap

The blade is in osoraku zukuri style

The last image in the imgur link shows the hada, its is difficult to see, but emerges in the right lighting. It is a bit similar to a edo period wakizashi i have

the kissaki is swelled, as seen on one of the last images

there is a flower mon on the koshirae and the hairpin, the kogatana is missing sadly :/ 

I have not found a way to remove the handle, so looking at the nakago is difficult, i know this makes identification harder

 

Any info or thoughts are appreciated

Oof. Koshirae is nice. But that is a LOT of kissaki missing. I would see if you can see the boshi in the right light. That will tell you if it's saveable. Hopefully so, the osoraku-zukuri shape helps in this case, hopefully there is enough hamon to reshape. It's an interesting shape, and hard to date what's there. If the hamon runs off, you have an interesting metal tsunag in plain but nicely done koshirae. Since polish is per inch, this may be worthwhile having properly polished IF the boshi exists afterwards.

Agree with Brian - at least the koshirae is nice and would be the bulk of the value. It looks as if the mekugi is some sort of double pin (with one side missing). Could the remaining pin be punched out from the other side or do you think it is glued?

Wanted to add that the design, materials, and workmanship on the kashira are very reminiscent of a metalworks factory called Ryubun-do.

I have tried, but the pin seams to be stuck, i suspect glued

If its Ryubun-do, would that date the koshirae atleast to between 18-1900?

Unknown. The koshirae could have been mounted to the blade at any time and the ryubun-do factory has been around since 1735 to the 1950s (not positive about the dates. Depends which article you read). The design used on the kashira and materials look to be Meiji or possibly Taisho. Here is another example of their work from Meiji where you can see the similarities in style and materials.

Theoretically, could it not be reshaped into a much smaller tanto? Similiar to how a naginata-naoshi has some of its boshi removed, I wonder if the same could be done to this blade being that it is an osoraku tanto.

[PNSSHOGUN]

Depends heavily on where the Boshi terminates, the quality of the dagger, and whether of all of these are worth the cost (noting you are not close to a Togishi).

 

The Mekugi ana looks to be a screw in type, with one half missing.

good point, it looks realy similar atleast. Nice to have a lead to read up on. Thanks!

[Karasunoir]

Its hard to see in the rough state the kissaki is, but i am pretty certan the boshi runs out. Im pretty sure the cost would be to mutch for my wallet at the time, but ill keep it oiled and preserve it as good as possible. Mabye it can be revigored some time in the future
