First, thanks in advance for any help. Just started looking into two swords I inherited and am amazed at the spirit of the community of sword collectors.
Grandpa was Seabee and collected two swords in WWII. They were well cared for and in good polish. They are not gunto, I'm quite sure, from what I have seen looking online at swords and fittings.
Sword 1 is Wakizashi with fairly clear mei. I was able to figure out 6 of the 7 characters myself, thanks to all the very helpful websites around, but I am stumped on the 6th. I can tell that it is not certain characters but have not been able to match any complete mei in the databases available. Sword feels heavy, like it may have been cut down, straight hamon, not able to characterize boshi. Sword 2 is beautiful mumei Katana, will post pictures later.
I'm not going to tell the characters I translated so you can enjoy the delight in arriving at the answer like I did. Just need that 6th character. Enjoy
