White Nomad Posted March 11, 2021 Share Posted March 11, 2021 I'm not sure where to post this, but I figured here seeing as it's to do with reactions and such. So the story is, I'd made myself a machete from some mild steel flatbar (not sure what SAE exactly, just from the hardware store) and I was using it while gardening just to see how it worked. I was hacking into a palm tree which had to be removes and the sap/tree juice was staining the metal a weird blue purple colour. This coating would really whipe off and I had to take to the blade with some fine grit paper to remove it. Does anyone know what's going on here? Is something in the tree reacting with the metal? If you know anything do let me know. Quote Link to comment Share on other sites More sharing options...
