A customer asked me if I could fix his Kiritsuke tip as someone had previously rounded it. I am not sure the best approach, do I just sharpen it but don't lift the tip much until it's back to a point or should I just regrind it on a belt sander (I have a Ken Onion Work Sharp I can use on low speed)
I found how the knife should look so any suggestions are welcome.
The thing is, the tip has been rounded out by removing metal, so there is no real way to bring everything back to how it should be. If you want to restore the angle of the tip as it was initially, the best option would probably be to sand one or two millimeters out of the entire height of the blade end, at the original angle.
As it is heavy work, and probably not that important, I would go the belt sander or wheel side way for just a tiny bit to reduce the bevel at the tip and bring it closer to a point.
Then sharpen it as required. You may have to lift the tip a tiny bit, and/or pivot slightly, depending on how the bevel goes at the tip.
Lifting does not round out the tip if done properly, keeping the tip clear from the stone's shoulders until the end. But it should barely be required here, as the edge does not curve upward too much. If anything, lifting increases the angle, so it reduces bevel height, which is exactly what you want in this case at the tip. Don't pivot away from you too much.
I think knife restoration experts such as @Kwakster will have dealt with much worse and could provide useful insight...

Thanks for the information, I'll give it a try.
