I get that you use what you have, im all for that. But why didnt they just use water?!?! Its literally the most cost free thing on this planet and is far less.... disgusting.
Because using water would crystallize the metal and would make it fragile.. Not a good idea. But I have made some where around 50 or 60 blades and used engine oil will work just fine if you don't mind having to polish it. A lot!!
