Sandblasting a Sword?

[Jeff D]

Hi all,

Has anyone here tried sand blasting a heavily rusted sword? I have a few projects which are heavily corroded which I would like to try it on. I have in the past tried the usual iron wool, oil and time, but, I find that it doesn't get the oxide out of the pits and grooves which could be hiding markings.
I will show a trial run I made on a old rusty square. It seems to work fairly quick. I would appreciate any tips and/or advice.

Thanks Jeff
