Good grief! Machetes were born in the jungle, it's what they're made to do, for crissakes.... and I'm pretty certain none of them were made of "stainless" steel. I used them in Vietnam, and Guatemala...they won't rust away if you take care to clean and oil, as often as necessary or even only as often as you can. It's been a long time since I've seen a jungle (but I have been to New Orleans. LOL) I have CS bowie....I love it. I have CS Bolo machete ....meh...handle sucks. I have CS Gladius....marvelous, specially if you like to pretend you're killing your girlfriend's Greek relatives ( kidding, I love her relatives...can they ever cook!) Back to the point....NONE of all the CS knives, swords....or MACHETES I own (over a couple dozen, Cold Steel knives, not a couple dozen machetes, for crissakes)) have ever rusted. Ever! So, just take care of the damn things and....Relax!
