Hi all,

So this is the kissaki from a 28'' blade signed tachi mei.Over all the blade may be ok... except for the kissaki I think?Does it look to anyone to be badly reshaped or damaged or is it just me. Can it be "fixed" if there is enough tempered steel left ?

Marcello, it may be the angle of your shot, but it looks like much of the niku is gone from the kissaki. I agree it looks strange, but I can't think of any way to reshape that part of the blade. Hopefully, one of our togishi will have a better idea, but in the meantime, could you take another photo showing the entire boshi directly from the side? I think that would make things clearer.

Yes, this kissaki is poorly shaped. And yes, the boshi is what you need to look at. Try to imagine how much metal would need be removed to make the kissaki shape correct, and see if that would allow the boshi to still exist without running off the blade at any point. If there is enough boshi, reshaping the kissaki can be easily done by a togishi.

I've been trying to visualize what the correct shpe would be if it could be reshaped? I marked out two versions very badly done :lol: !! I'm at work and only have acess to MS paint no PS on my machine lol...Are these even close to what should be there?

Ideally as little steel is removed as possible.....This looks to have had a chip at the midpoint in the kissaki. You should verify what is left of the boshi before you get too carried away trying to determine how it should be reshaped. The boshi will tell you how it will need to be done, if it is possible at all....

Thanks chris...I was just throwing it out there to start some discussion so that newbie's like myself might learn some basics,and I did...I didn't even think of the idea that a chip would be the cause of the dip in the line of the kissaki but that makes perfect sense now.I figured it was just butchered by someone trying to sharpen the tip.

Marcello,

A polisher will often remove material from the mune, decreasing the sori a bit in the process, rather than take all the reshaping from the ha of the kissaki. With this technique you are more likely to have a salvageable kissaki.

However, the 1st question isn't, can this kissaki be reshaped, rather, is this sword worth the bother? Reshaping and a polish will be expensive if done properly; are you sure the sword warrants the effort and expense?

Hey Grey,......not sure if it's worth it but I figured I try and find out if it is even worth looking into I know the kissaki is a rather expensive and delicate area to fix.It's probably not worth the expense or may be a wash?I'm trying to learn what kind of expense this type of repair is and what can and can't be repaired.By the way that tachi went back to seller I asked you about.
