I've learned a lot just reading this forum but now I have a question. I have a kitchen knife that has seen constant use for 32 years and has developed a bow in the blade. You can see the gap in the second picture.

I am getting a Sharpmaker for maintaining a keen edge on my kitchen knives. My question is what do I use to level out this blade? Can I just buy an inexpensive course stone?

I'd appreciate advice on both what stone to get and how to use it on this knife. Thanks.
 
when you get the sharpmaker just lay some sandpaper on a flat surface then sand the edge by going in an inline motion until the edge is straight. then you can resharpen the whole edge with the sharpmaker. you can also work on just the high spots with a piece of sandpaper and a small block.
 
Was that knife maintained with a grooved steel? Those can put a bow in a blade like that over time.

The sand paper idea is a good one. Use wet/dry paper and you can tape it to a sheet of glass for a really flat hard surface, but that is not absolutely necessary.

For the effort involved, you could just buy a new knife, but maybe you have some attachment to that one or just want a challenge.
 
It looks like uneven sharpening/steeling over the course of 32 years -not that it is excessive.

If it were me, I'd leave it alone and just keep using it as-is.
 
32 years ? Buy a new knife ! Actually this is not uncommon .The end of the blade flexes while the blade near the handle doesn't .That means there is an area where the steel does more to the blade than farther out. The easiest way to prevent it is to steel only the flexible part of the blade !! You could take a coarse stone and remove material at the end of the blade and start over .
 
WOW, those are some big pics!

I had the same thing happen with one of my kitchen knives over a much shorter period of time. . . The result of using a grooved steel as some have mentioned. I just used a cheap coarse diamond stone from Harbor freight to level it out. I'm sure that sandpaper on a smooth surface would work just fine too. It really doesn't take much time or effort. I don't see any reason that you couldn't get another 32 years of use out of that knife.
 
Thanks for all the advice. This is my first first post with pics and not sure why they show up so large.

What grit sandpaper would work well?
