Too thin of edge at quench, got a ripple.

So, it's one tiny little spot on the blade, about a quarter inch deep, and long.

I'm sure I can grind it out. In fact, I sort of left the edge at a tapering thickness just so I could see how thin is too thin as an experiment.

It was Aldo's 80crV2, I let it soak at between 1495 - 1515 for 10 minutes or so. Gas forge, so not as precise of temp control, but I feel I'm well within the limits of the steel. If my reading was correct, the bit of vanadium helps prevent grain growth. Doesen't that give a bit of cushion?

Quenched in Parks 50, 5 seconds or so, and took out a little warpage, then back in. File skated nicely after room temp, just barely scratched the black off.

It's sitting in the oven now at 400F.

Any tips on the small ripple? Pretty sure my first instinct is the right one (grind it out) ha ha.





I guess I should add that this knife was the first one that I forged from bar stock, here it is right after I knocked the scale off.

How thick was the edge at HT? Probably a result of it being to thin along with uneven heat due to austenizing in the forge.
 
Heat was very even, used a super thick baffle I made from an oil field pipe. The edge was thin where the ripple was. Didn't measure.
