Guessing it was too thin?

Pretty sure the edge was simply too thin but thought I would post these out here and get opinions. It's Aldo's 1084 heated to non magnetic and quenched in Canola at about 140°. It took a little warp as well as the rippled edge.

I figured since it is pretty well gone anyway, I have clamped the edge between two pieces of angle to see how much will pull out. Not holding any hope for that one.



 
Clamping will not fix that ripple....you have to over correct to get a bow straight. I would do as Jesse suggested.
 
No harm in just grinding it back and making a bit smaller knife out of it. Lesson learned. Had a hunter Darrin Sanders heat treated for me do the same thing when I ground it way too thin. I was gonna junk it and Darrin told me not to scrap it and it still turned out very nice when I just ground it back.

You may be surprised how little edge you will lose. I've had that happen. I just grind like normal after the temper, then re-profile the dips out. Jess
 
I had to take about an 1/8" off but even at that there is a spot that you can see slight bit of ripple but the edge is good. Time will tell if the HT and temper are good. As much as I try to make new mistakes with each knife I am sure I have some recycled ones here in my third try.

 
I've fixed far worse. It can be done it just takes a few heats is all. Be creative in your approach and you will be surprised at what can be accomplished.
 
Are you scribing lines on your edge to follow? It looks like it's pretty thick towards the plunges but really thin where it warped.
 
A trick to lessen the chances to get those ripples is entering the quenchant spine first, or spine biased when entering point down
