Zero corrosion after leaving wet tree sap on the blade for several days. I'm going to move forward with 3 steels for this model. 52100 for ultra demanding use and cold weather, NITRO V for swamps, tropics, and costal climates, and 3V just because its awesome. After thorough testing I think NITRO V has better edge stability that 52100 but is not as tough. This is especially evident when you break the blades in a vice. After you get past 90-100 degrees NITRO V will break while 52100 will take a permanent bend. This is a tradeoff with stainless and is to be expected. Both 52100 and NITRO V can handle chopping through nasty material, batoning, repeated flexion, and having the spine beaten with a ball peen hammer and both will have a place at the table until something better comes along.
