I recently pickled one of my Model 5's and it turned out a little weird in that there is a real difference in how some of the blade came out very much darker than the rest of the blade. You can even feel where it changes color. Not sure if this indicates a heat or temper difference or something else. I used a rust eraser to see if I could even out the color but didn't make any difference. I may get the blade buffed out some or try some steel wool on it. Anyone else had this situation?
