Omi Yari thoughts?

[Tensho]

I'm fighting a losing battle with a junk phone camera and a setting sun. Anyone want to try and take a shot on what you think of this yari? I was thinking kanabo school, but partial mei doesn't add up to that.

[Tensho]

Couple more.

Mei is the last thing to look at, Matt, although few yari that I've seen are gimei. Almost looks like sunagashi, but something doesn't feel quite right.

The red laquered flame groove is very unusual. Long karakubi is the sign of an old blade. The blade seems to have gone through an acid treatment. Some pictures of the nakago will help. I agree with Ken, something doesn't feel quite right.

The kusabi-hi isn't that unusual. I have only seen a few yari that have it though.

 

Mei is very badly corroded. Looks to have been a 5 character mei at one point.

You are right, such grooves are not unusual. I wanted to say that it's shape appears to me peculiar. The nakago seems to be very old, possibly koto era.

[Mark S.]

I would agree older, but I also agree it looks to have had an acid etching and the nakago has been sanded down or something else to try to expose mei.  Unfortunately there are a couple eBay sellers who are notorious for both these practices.  I can ‘almost’ understand MINOR cleaning up RED rust (only) on nakago to view mei, but there are few blades that exhibit that type of activity without some serious acid help.

This is the nakago without direct sunlight.  I can see why the photos in sun are making it look weird. I did clean the mei area with ivory as it had a lot of active rust. I bought it as mumei

And for the heck of it,, what it looks like without direct sunlight.
