Katana original ?

I cant rekove handle

[werecow]

It's a WWII shin gunto (sometimes they have older blades but hard to say). I know there are some fakes out there but I'm not very well versed in them, though fwiw I don't see anything suspicious.

Hi,
Just add DW40 above the guard, shake up and down the hilt and press the silver button on the fushi.
Normally you will be able to remove the tsuka.
Best wishes,

Definitely original.
Never clean the handle/nakago, aside of some oil/wd40 and gentle rubbing with a cloth.

aspalathos,

Pieje is correct. Never clean the tang beyond a bit of WD40 and a soft cloth. I advise you to check out the Nihonto Message Board forum for full advice on the care and feeding of Japanese swords. It is a world unto itself and if you don't know what to do, you can make a grave error that will damage your piece and significantly erode its value. Your blade has a signature which means that it is at least a cut above the entirely factory made blades. Someone on the message board will be able to translate the signature.

Sincerely,
RobT
