Howdy all. I love Ontario knives. I had a rat 1 and it had a bit of blade play that I wasn’t comfortable with and also the lock would defeat with just a slight spine tap so I returned it. Anyway I just got an Ontario 499 cause it’s a badass and iconic knife. I know that the 499 has a date on the pommel but it seems like almost all of the 499’s are dated 3/11. So did the just make like a million in march of 2011 and they are just sitting in warehouses? Also how do you keep the blade from getting scratched on the rivets when you put it in And take it out of the sheath? There are 2 rivets that are attached to the sharpening stone compartment that scratch the blade. Thanks!
