yeah I agree with leighman, Victorinox i.e. Swisstool and Spirit are more corrosion resistant, I believe it's in the treating. LMs are stainless but for some reason don't repel corrosion as well, but their not bad, just not as good.
yeah it's the new LM sheaths that suck! their like cheap plastic (theirs that word again!).
our many delays here is another bone to pick! grrrrr
it's coming.
