A little rust is not a threat. However if it gets out of hand it tends to get out of hand in places where water is traped like at the edge of the scale. Rust that sits and grows too long starts to pit the metal...and if that pitting gets out of hand, and bunches up let's say along a straight line...like the end of a scale...theoretically that blade gets a thin spot. This is pretty hypothetical as it would take a very long time for such a thing to weaken a blade...unless it were in very bad conditions like in a salt water fishing boat tackle box, stored aboard. Just wipe 'er down with a little oil every once in a while and you'll never have any rust issues.
Dude, I'm trying to contribute and bring you into the fold. Don't lash out. Knives get a bad rap from the uninitiated and a lot of folks are working very hard to fight back. "Vakra" is one thing (that's their Kukri). "Felon"...that's just a plain stupid name for a big knife...stupid marketing...why not just call it the "Alamo Special" or something. "Felon"...epic fail there.
