Take a look at this pic I took for you. Its lousy in quality but it shows quite a bit.
Look at how much fuller the blade is on the factory fresh 85. This is the knife I learned to peen pins on. You can see how I had to sand off some depth of the serial number to clean up my learning work. The satin finish is not showing through the patina that took a long while to form through use and carry. I worked over the entire knife, but I NEVER stained or did anything to darken the wood, but it darkened from hand oils, grease, grime, dirt and sweat. I sharpen ONLY with a translucent Arkansas stone and finishing strops. I never over sharpened, I have practice with that and I don't just sit there honing away wondering why its not sharp yet. The knife has been through a lot, dropped in water, dropped on concrete multiple times. Talk about not letting a blade snap shut, give me a break. I use this knife and I don't care to have to use two hands to close it. Grab it, open, cut, snap closed on my jeans...
