Thankfully the second blade has not etching but the stamps are on the shank so that works out lol what can u do? I had to muck up sometime it's just too bad it was on this blade.... I can keep kicking myself in the ass or just move on and realize I have 115 other blades to worry about and learn from this one... Never touch anything with a stamp to greaseless to remove patina, patina>pitting so it's better just to leave it as is
