I took the knife to 32 degrees and it sprung back to true. It may have gone farther and sprung back to true, but we did not test it for "return to true" after the 32 degree mark. Also realize that this knife tested out at 59.2 rockwell.
You should also realize that I park in at just about 300lbs and pulling just on the handle (no pry-bar) I could only get it to bend to 20 degress.
With the 4ft pry-bar and one of our guys coming in at 250 lbs doing the bend developed arm tremors that lasted for almost an hour after the photo shoot.
As I told you earlier, you will simply be amazed at the toughness and performance of this knife.
