I stripped my entire 16, blade and under the handle. When I added stainless steel hardware, I dipped the threads in some oil in case moisture gets under the scales through the bolt holes. I took my 16 out while I was sledding with the extended family in the New Mexico mountains in December just to see how it carried in some non typical situations (diving off a speeding sled, rolling down a snowy hill, catching people at the bottom of the hill before they ramp off into the parking lot...). Of course, everyone gave me "what for" about taking a knife sledding (none of them even know what a Becker is, despite the fact that I have made many attempts to educate them. None of them, uncles and older male cousins included, don't even own a fixed blade knife of any size.) Wore it on my belt the entire time. After a couple of hours, we got back to the cabin and the knife and sheath (stock) were soaked, and probably had been since I left the cabin. All I did was take the handles apart, dry everything off real good, and oiled the blade and the screw threads again. There was no rust on any part of the knife. I did leave the knife out of the sheath until I was absolutely positive that the sheath was 100% dry. Still haven't had any rust issues at all.
The moral of this story is that you probably won't have any problems with rust under the handles as long as you don't outright neglect it, or swim with it in salt water...
