I was told that the shiny stuff was probably shellac or varnish that someone applied to the blade at one point as a protective measure. However, I was also told that in days to come, this coating will do more harm than good so I'm going to need to find a way to get it off without damaging the metal at all so I'll probably have to look into having a professional do it for me so I don't mess up a good sword. x.x
