Your Guess on era on these two blades

[Utopianarian]

What era would you guess each of these blades just based on these pics would you guess? They do both have loose grain and openings throughout the blade and have the kazu uchi mono indicators in my opinion but also could be masa ware due to the grain structure in the hada.

Left looks like earlier Muromachi and right appears later - Sue Bizen perhaps. Nice early style Shin Gunto mounts for at least one of them, any more pictures of the mounts?

Hey John, Yes definitely have pics. Love the color of the saya on this one. I just can’t get enough of the older blades dressed in Gunto. Looks like the saya was also marked or signed which is unusual. Maybe the owner thought he would get it returned one day before surrendering the sword. My brother on the east coast came across this one. I think it was one of those true unmolested Gunto finds that wasn’t messed with or swapped for parts etc.. I think the tassell was original to the fittings as well..,

The Chuso unfortunately was broken so it didn’t lock in place. I sent my brother a Chuso I had got years ago from an old guy on Craigslist from Nevada and took a chance by mailing him a check for $25 which eventually he mailed it to me. I knew the Chuso would have a use one day. Hope it fits when my brother gets it

Good find, I assume the Saya in the first post is for the other sword? They look like the nice early mounts.

Yes that was the other sword. I gave that one to my brother as a gift. I think I posted that one a ways back. I asked him to take a pic of them side by side. I assumed they are both war blades from Muromachi. I agree your assessment of these blades is spot on!! Thank you John

I feel fortunate in the respect that I happen to live in the US to hunt down these type of blades. It is however becoming harder and harder to find them. I wish when I was young when all the WW2 guys including my grandfather was around at the VFW with his buddies drinking lol… could have had a lot more exposure to the things they brought back. I was probably in my young teens then and was more into playing with plastic toy soldiers in the dirt than Guntos lol

the one on the right feels like either 1630-1640, or maybe even after Kambun.

First to the left feels like it might be anytime around 1520-1620.

Big maybe in both cases.

Without measures (nagasa, sori, motohaba, kasane) it is impossible to say anything. That said, the sword on the right seems Bizen and, considering the shape of the nakago I would say Sue Bizen or after.
