Not gonna do it again anytime soon, but you're overestimating the risk, I could be badly injured, yet unless it shot a knife into my eye I can't see how it would kill me. I love my fingers though, and now I don't need anymore spring... As I said I won't do it again and this topic is meant to warn others (though it seems like everybody already knows)
The leaf spring was properly clamped of course, and it had less pressure, also the flat surface and shorter movement up made it easier to dismantle, I'm going to use that rather than coil from now on, the metal shape is also much more compatible with forging.
It was kind of a joke, my forge is a coated grill connected to a vaccuum cleaner (that can actually melt steel but that doesn't matter) and I have no anvil, so I've been looking a lot for blacksmiths in my area who's shops I could raid but I found only industrial metal workers who focus on houses and stuff I don't need. I used "blacksmiths" as the more traditional ones, and those stack in the north, I've heard of about four workshops.
