Grey, thanks for your reply and tip!
Took a quick look at your website and i can see you are deeply immersed in the sword thing-- neat.
Some questions if you don't mind:
Can you tell me what is the powder the guy uses in the embedded video in my posting?
What specific oil is best to use?
Would some sort of solvent (if any) be good to use on the blade to remove any contamination from acids or such from people touching the blade w/ ungloved hands, before re-oiling?
Any other tips or recommended things to do for care and maintenance?
I think from now on i will only handle the sword w/ gloved hands, either cotton or nitrile- good practice?
fyi, i have attached 3 pics of the Gunto.
Thanks,
dwp
