WW2 Japanese sword

[Jason 84]

Hi all, can someone please help with any info about this sword? All I know about it is my grandfather brought it home from new Guinea during ww2 and said it was an officers sword, it has some inscription on the tang but im not sure of translation either a name katsunaga or maybe individual words as victory forever? I really have no idea any help would be much appreciated, thanks

Jason,

welcome to the NMB forum!

The signature does indeed look like KATSUNAGA. The only photo that can give us some information on the HAMON lets me believe that this is an oil-quenched military blade, made for WWII. If you could make some more close-up photos without you throwing your shadow on the item, we could perhaps see and help more.
