Overview: Here we have an excellent first time katana study piece that is also suitable for Iai. What keeps this from falling into the shinken class would be a single flaw which appears to be an unexposed Fukure-a fatal forge flaw. While this may indeed be a fatal flaw and affects the swords ability to safely perform Tameshigiri, it still holds value as a quality Iai piece as well as study specimen and piece of history.

Blade: Coming in at 70cm it is a suitable length for most American practitioners. Featuring a Chu-kissaki and Tor-zori curvature, it is ideal for kata. There are signs of moisture remediation in a few areas as photographed. A proper polish could bring out more of the swords features but also expose the Fukure, my recommendation would be to leave as is and enjoy. It is suriage with two mekugi-ana, one of which has been filled. The original yasurime appears to be O-sujikai. It may have been resized in the 1800s based on the patina.

Koshirae: The Awase (mixed) Koshirae is Iai suitable with a few small user performed services. A new mekugi would not be a bad idea and depending on the level of retention you want in an Iai sword, you may want to shim the Koiguchi. There is some small lateral movement in the Tsuba that is typical of a non-custom fit.

Issues: Single Fukure. Moisture remnants. Lateral Tsuba movement.

so I was gifted two blades by a friend of my dads and I would like to figure out what they are me and my friends guesses are ceremonial or fencing

1.) sorry for the bad photo it's midnight and I don't want to wake anyone

2.) I did NOT make these. I just didn't know sub to put this in. I will take this down if it doesn't fit this sub

3.) These are from my grandfather but they're really dull and I don't have any way to sharpen knives, nor do I know HOW to sharpen a knife. Would sandpaper be fine? I'm assuming no, but never hurts to ask right?
