Ummmm... I doubt that there is any BT left on my Cub, anywhere except under the scales, where I meant to leave it. Here is why:
I removed anywhere from about 0.5 to about 3 mm from the spine of my Cub. Yes, that's 3mm! Or even more. I completely ground off the thumb ramp, from just above the scales all the way out to where the swedge starts on the blade. Gone! Additionally, I initially used 400 grit sandpaper (not 3m scrub pad or Scotchbrite) to remove the BT from the sides of the blade. The I went to 600 grit, IIRC, and finally went to a polishing wheel coated in jewelers' rouge. So, I removed more than a few molecules from the spine and the flats of the blade.
I carry it all the time, but not against my skin or inside my shirt; just under a coat or sweater. So, it is not in contact with my sweat. However, I do live right on the shore of the Chesapeake Bay, where the wind whips up the water enough sometimes that you can smell the salt in the air. In any case, it's isn't corroding or staining at all.
Sorry it took so long for me to reply. I wish I had a digital camera, or a scanner that I could get an image of my Cub. But, it has changed quite a bit from when it left the factory. It is a worker, and looks it. The M2 is awesome.
