I recently bought a Ronin Katana Dojo Pro made from 1060 hardened steel (awesome sword) but I've managed to bend the tip of my blade with a bad thrust... I've googled "bent Kissaki" and while reading through similar problems I noted that bending it back in place could cause the steel to break which would mean I have to polish or file the blade to form a new kissaki. That's something I'd be sketchy about doing. Another option I came across was to send the blade to a blacksmith to have it fixed but that's something I'd like to avoid if it's possible for me to fix myself. I decided to go ahead and join the forum and make this my first thread. Hopefully I can get some good feedback on what the best course of action would be to preserve my blade. It's a brand new sword so I'ma be patient and make a solid decision before I try working on it. Here are some pics showing the curl... I look forward to your responses -TJ

I can't be of help with the repair... But, from the look of it, I'm guessing it was a pretty good thrust. Maybe just poorly aimed? What the heck did you stick with it?

I'd file the damaged tip off and reshape the kissaki. If you work patiently, you might come out of it with a stylish ko kissaki sort of thing. Be sure to file a nice even curve along the ha from yokote to tip and then smooth it out with 400 grit, 600, and 1500 automotive sandpaper or polishing stones to get a nice, smooth finish.

I cut a box and followed up the swing with a jab into the chopped off portion which was laying on the ground. The blade went through the box and the tip hit the carpet which I'm assuming has concrete underneath. Needless to say I'm pretty disappointed in myself.

Ouch. I can imagine your reaction. I'm actually somewhat surprised I haven't damaged a sword blade, yet; but I know I will beat myself up pretty badly for it when it happens. Best of luck on the repair.

I'm considering that, thanks for the image and sandpaper info.

I was gonna say it looks like it hit the floor lol. Had a cheness do the same thing, i filed it flat so cut the roll off, dont even bother bending it. Then filed, sanded and re adjusted the kissaki. Did the job, just time consuming...

Alternative is a ball peen hammer, heat the tip till dull red then tap back into place against a heavy vice or section of rail line.

For what you've got there, i would avoid the torch, and stick with file work and a cold blade. Just like joe said, file the bent portion away, mark your new profile line, and bring it slowly bak to it's new shape. I'd be worried about over heating, and screwing up the temper of the tip, which will make for a recurrence of this issue down the road. I wouldn't worry about screwing it up at all, filing steel is a pretty slow process, and it's super easy to see when/if you get off course. Just take your time and pay attention.

I went ahead and filed down the kissaki and used an accusharp on it afterwards. The blade is almost perfect and only took about 45 mins to finish it. Appreciate the tips guys

Good to hear! I had a similar incident years ago. One of the first things I did with my first decent katana (Cheness Tenchi) was to drive the kissaki into the hard ceiling, bending the tip slightly. Luckily it was fairly easy to fix.

Situations like that are stressful I'm glad it was relatively easy to fix.
