A file will always bite into the decarb layer, and it must be sanded thru in order to reach the hardened steel.

Can't tell you how many times this has been the culprit in instances like this. It's nearly always decarb. Then temps being off. Then wrong steel ID.

No I had not accounted for that. I hope you are correct. Regardless, you've brightened my day and given me renewed hope!

And thanks to everyone for your help. I'll report on the edge when I check the results this evening.
