Im curious if this has ever been reported. Asking because a sword ive only used to cut yoga mats and pool noodles somehow has a tiny roll in the edge. Not sure if its a quenching issue or not.

Soft targets can not roll a steel edge. 1) Did you buy the sword new? 2) Did you inspect the sword and KNOW the roll wasn't there when you got it? 3) Who is the maker?

It's an old kaneie. Bought it second hand from user kaiyo, he apparently only collects and doesn't cut with his swords. It's so small I didn't notice it on initial inspection when I first got it, so have no idea if it existed beforehand. Also he is the first owner Attachments:

If you were cutting CLEAN soft targets they could not do that to your sword no matter how bad the heat treat. If there was a rick/pebble on the target it is "possible" that "might" have done it. Most likely you got it that way...but your failure to inspect the sword carefully will keep you from ever knowing for sure. Hopefully a lesson learned on inspecting edges on all swords, but particularly second hand ones. As for the prior owner, I am sure it was a little old lady from Pasadena who never cut with it and only fondled it on Sundays.... How much did you pay for the sword?

I paid 1k for it due to the fact its an older kaneie and rather rare. I could try and get someone from my dojo to fix that spot and it probably wouldnt cost me much. still a little disappointed though.

Kurin/Kanei is supposed to have a pretty hard and rolling resistant hamon. If you got it like that maybe he hit hard targets? It’s that type of abuse that caused edge deformation in mine.

I plan on continue cutting with it, and if i face similar issues i may go to the previous owner and request a refund. Not that it is necessarily his fault, especially if he never cut with it, but I bought the sword for use, not to look pretty on a sword rack

You got a point. The geometry in these swords is really nice. I wouldn’t risk it with anything like a sharpener

That’s the best solution, let someone who knows what’s he’s doing polish/sharpen that part.

Stropping should not give a secondary bevel, but I don’t think that will be the fix. Stropping doesn’t amount to more than an ultra-fine polish. Honing, the next step up, probably won’t either. For the first fix attempt I would not recommend either nor any attempt that involves metal removal but to realign the edge. Try this, it worked for another chap on his katana and for me but not on a katana. Using a smooth piece of hard steel try to bend the roll back into shape. I’ve done it using a knife’s spine and of late been using a chakmak on all of my knives after use and that seems to make them last longer between a true sharpening. The video will explain. FWIW the in the video the narrator reverses the direction of the chakmak and I use the same direction on both sides, as if that will make a difference. I would like to know the results. If that fails let someone that knows what they are doing handle it.

I do most of my "sharpening" (edge roll realignment) with a butcher's steel. I've used the same one on several of my katana.
A more aggressive strop might get the roll out, but may also affect the polish.

As a team caution stool pigeon I’m bound to tell you the polish ok these and their geometry is really nice. One tiny spot won’t really affect your performance but if the good geo is lost that might.
Could you use pure coper or another soft metal to try and correct the roll?

Use a soft metal drift and try to smooth it out. Do the absolute minimum required. You will never ever notice such a small defect when cutting.

If it does end up being an actual issue with the quenching(dont think it was because i went thru the cap of some water bottles and nothing rolled) then ill see if the seller would be willing to atleast give a partial refund. My ocd brain makes these little stupid things bother me lol.

But for me if it was my katana the psychological effect is another thing. I’ve not known of a smooth hard steel rod or narrow bar causing damage, that is why I recommended it over any abrasive regardless of fineness. Use it at an angle as described in the video where it touches the ‘edge’ only. Soft metals will not work as the material needs to be harder than the blade.

Before I do any of this I'm going to wait for the polisher from my dojo to respond to see what he has to say. If he can fix it for relatively little money, I'll just bring it to him
