interesting Japanese dagger similar to a forester's dagger

[messia]

Hello everybody.
At one auction they put up an interesting Japanese dagger similar to a forester's dagger.
But there are many differences. What do you think about this dagger?

Looks like a standard forester's dagger for Hanninkan Stationmaster, but with a second Haikan added. The Haikan is clearly from a different dagger and looks very unbalanced.

Oh, I now see that the Haikan has a ring only on one side, so back to the search.

Looks line there has been a ring on the other side

[Nick Komiya]

Now, I'm fairly certain this is a Frankenstein Forester with swapped Haikan. Police and fire brigade daggers had their Haikan rings omitted on one side in August 1942 as shown below, but there is no record of this happening to a forester's dagger.

The one in question, in my opinion, is a forester dagger with post-1942 police dagger haikan added along with a second haikan from elsewhere that should not be there at all.

It dosent look like a rope Haiken.

[Nick Komiya]

I was not referring to the rope-style Haikan, as all Haikan on police daggers got rings omitted on one side in 1942. See announcement below.

I agree the second ring looks "out of place" on this scabbard. I don't think you have stumbled upon a rare treasure - I think you are looking at a piece part put together item that the seller/assembler is selling thru an auction to avoid having to prove this item is "original".
