I'll make it quick (on work time right now).
Work in a chemical facility, needed to draw a sample of copper sulphate for lab testing. Cut a small hole in the sling bag with my carbon steel Boker.
Copper was kinda wet and packed down, so I scooped some out into sample jar, then wiped the blade down.
What looked like tarnish is actually a copper plating...and I thought plating was difficult. We'll put it down as an alternative to etching, I'll bring in a couple of O-1 and HSS blades to see if this is specific to non-stainless steel.
I've extracted samples with bead-blasted stainless before and never had this happen. Can anyone shed a more scientific light on what just happened?
