Thank you all for the fast help! I've been looking online regarding kaneaki, some swords from this province have kuriyama kaneaki but this one doesn't is there any reason it's omitted? This sword was from my greatgrandfathers who fought in the pacific, Maurice LeMay, his cousin Curtis gave it to him while they were both there.
The blade seems stuck in the saya which is unfortunate because I was hoping to find a way to restore it but don't want to break either of the pieces by prying it out.
