This dent just won't die...

This is the most stubborn dent I've ever tried to grind out. I don't know what the edge hit (probably a plate) since my ex-roomate threw it into the sink. This is after quite a bit of work on it with a 220 grit waterstone...

Instead of the depth diminishing, it's staying the same and it's just getting longer. I supper that means I'm just gonna have to wear away the steel around it until its at the same depth? Seems like a waste, and the time it's taking is irritating me. Still it bugs me to have a big dent like that on there...

Wondering if I should just kick the angle up to grind it out quicker, then thin it back down.

You've the right idea. For fixing big dents, I usually sharpie the dented edge area, then use either dmt xxc or xc to grind 60* per side until apex, then 30*, then 15* (or whatever target angle). finer grit progression from there.
 
Unless the dent causes some problem other than just in your mind, I would just sharpen it and go on down the road. Eventually after numerous sharpenings, it will work itself out without losing so much steel up front, and diminishing the life of the blade. Just a thought.

That would be my approach as well, with as small as it is, I would probably just ignore it. Additional work will easily remove it entirely, but is it worth the time and metal removed from the blade?
 
It looks rolled to me...maybe. Toward the penny. Maybe try steeling and see if you can't push that back. Look at how the light is on that dent. If dented from the side toward the camera that steel had to go somewhere...it didn't compress. It probably moved...bent...toward the penny. If you haven't got a steel try a stainless steel sink or something, hold the penny side of the blade against the steel and work it back and forth and see if it doesn't straighten back up.

Oh you're 100% correct that it was rolled a little too, but so much so that it looked like the edge had been folded over to a 90 degree angle relative to the rest of it. I think what is still visible is the portion that just keeps kind of flopping back and forth.

Good idea on the steeling, might take care of that floppy wire at least. Unfortunately I only have a grooved steel.

I think I'm just gonna ler it slide though. Doesn't effect performance so it will come out in time. Lucky I have no pesky roommates to throw it in the sink now too :D
 
I wouldn't use the angle grinder on it. It takes material off too fast and generates too much heat.

What type of knife is it? If it a kitchen knife, chances are that you could probably use a file to re bevel it, then finish up on your stone. I've done this to a few kitchen knives.

Looks very minor, I would just ignore it. With use and sharpening over time it will gradually dissapear.
 
I don't think a grooved steel would be a problem. Just go over that area, spine leading a few times and see if she stands back up. If not (or not completely) they by all means, move on and indeed future sharpening will take care of it.
 
Regrind it and be happy with your blade for as long as you'll have it, instead of having to wait for it to be the way you want it. Moving the edge up a couple of millimeters won't drastically change the time you'll have with it.
