Spent a week trying to fix a weird crack in a blade I was making

I was working on a chef's knife from 1084 steel, and after the quench, a tiny hairline crack showed up near the spine. I figured I could just grind it out, but it kept chasing deeper. I ended up having to anneal the whole thing, cut the cracked section off, and reforge the tip. What should have been a one-day fix turned into seven days of rework. Has anyone else had a crack that just wouldn't stop?

Ugh, that's the worst kind of crack. Honestly, I get what @logan205 is saying about leaving it as character, but with a chef's knife near the spine, that's a ton of stress right there. Tbh, once a crack starts running like that in 1084, grinding almost never catches it. You did the only real fix, even if it took forever. It's brutal, but starting over from annealed is better than having it fail later.

Oh man, chasing a crack like that is the worst. It's like the steel version of trying to fix one typo in a text and then your whole message just turns into gibberish. You think you're being smart by grinding a little more, and then suddenly you're holding a knife that's basically a fancy letter opener. Been there, done that, got the t-shirt and then burned it in the forge out of spite.

That feeling hits way beyond the shop too. It's like trying to clean one stain on a shirt and you rub a hole right through the fabric. The whole "fix one thing, break everything" vibe is just how a lot of modern problems work. Makes you want to just leave the tiny crack alone and call it character sometimes.
