You can certainly interupt/arrest the oxidation and polish it out - maybe starting off with sparky's magic car battery charger and electolyte process - but there will probably be some residual pitting Aside from a full all over regrind, it will probably be left with some scarring, which will be where any future oxidation strikes first The edge itself will definitely come back in full working order.Let's see, you'll need a 230mm angle grinder, full face respirator, life insurance, 1kg of bananas, 2 litres of brandy and a Princess Leia outfit ... should have it sorted in about 6 hours assuming you don't get arrested first

Use as is!
Just try and not get blood on the camera when you take a pic of what's left of your face. Sent from my iPhone 5 using Tapatalk
