Recommendation? Bent 420 J2 Stainless Steel knife tip

420 J2 is a low-carbon stainless, which means it likely won't be hard enough, therefore brittle enough, to be broken easily. Such steels are formulated for flexibility and corrosion resistance, such as a fillet knife, for example. That should work in your favor, in bending the tip straight again. There's no harm in being careful in straightening it, but I don't think it's likely to break in doing so.

You might consider posting a picture of the bent tip on the blade, if you can. You'll gather more good advice from experts here on how to fix it, with a clear picture of how bad the bend is.

I tried posting a photo, didn't work. Reuploaded it through a link. Thanks!
 
Not sure if I'm seeing it accurately in the picture, but is the tip on that blade somewhat darkened, as compared to the rest of the blade?

I only ask because, if the tip has been overheated for some reason (which might darken the steel), that might affect whether it breaks or not. If it's been overheated to the extent the heat treat & temper are damaged, it can leave the steel weakened and/or brittle.

No, it's not darker, it's just the background and my phone's bad camera.
 
From what I am seeing in the picture it is a small section of the tip. I would place the knife between a couple of pieces of wood then place in a vice and go slow. I would be afraid that hammering it would be more likely to break off. There are no guarantees.
 
I doubt it will break, but anytime a blade takes a permanent bend, it has passed its yield strength and is much weaker. To bend it back to a straight position, you'll probably have to bend it past its original position by a bit, weakening it further.

Think of bending a paper clip back and forth. You can do it a few times, but it continually gets weaker with each new bend until it breaks.

But that's such a small amount of the tip that is bent, it probably doesn't matter. Even if the tip breaks now or in the future, it would not take much to grind a fresh point.
