/diy/ - Do It Yourself

It was doomed from the start since it was cracked already and I didn't see it until after I'd started heat treating. It was just old well-used metal saw blade from an antique store. My fault was not cleaning it up to shiny then examining it closely for defects. It was originally stock removal without heat treatment so the defects wouldn't have been a problem until rust could get to them decades later perhaps. But, those defects are killers once heat treating begins.

I had another knife snap for the same reason, using the same exact stock source, but it was the very tail end of the tang so it didn't matter. I just need to be more careful about cleaning then inspecting. I have the equipment to easily photograph at over 7x magnification (pic related, but resized for posting) so that won't be much of a problem.
