I Forge Iron

Drill it out or scrap it?

Ok. Do stress fractures come in groups, or can you just have one?

I've got a blade with some cracks that appear localized, and I was considering drilling them out in a decorative manner. Should the crack be considered a harbinger of a larger flaw in the steel, and the blade pounded out to scrap or practice metal?

Thanks!

Cracks can start propagating from scratches that occur due to grinding - either before or after quench. They act as a stress riser and the amount of stress in a hardened blade can be significant. Not annealing between forging and hardening processes can also cause cracks.
