Grandfather got it from WW2. It is steel and it is folded. It has the wave on the blade. Please help me figure this out.

Hi Patrick,

Could you do us a favor and post a photo of the full length nakago (tang) and a couple shots of the blade?

 

You have a Navy Officer sword, or kaigunto, that had a combat saya (scabbard) originally covered in leather.  The leather covers often go missing over time.  You can read about them here: Navy Officer Gunto - Ohmura site

 

Here's a good page for caring for your sword: Japanese Sword Care - Japaneseswordindex.com

Unusual to see a tag in such good condition!
