16 inch 1912 bayonet

[Major Tom]

The blade has been parkerized. How can I remove that finish?
Thank you

[Johnny P]

That may not be easy as it may have been sandblasted before Parkerizing. The blades were originally blued, and then polished back to white except for a small area in front of the guard. Then from the guard on back they were blued This one shows the bright blade except right where the date (1906) is.
