tune you're a godsend my friend, this is the most informative thing I've found to date and really explains a lot of details. I talked to a knife seller a few years back at a gun and knife show who had several Randall's and a sign advertising them to pick his brain for info. This guy proceeds to tell me that the market for Randall knives just isn't what it once was and tells me that my knife isn't one that is very sought after but he was generous enough to offer me $350. I put it back in my safe and haven't thought much about it until after my dad passed ( he loved it).
Sorry for the rant but thank you for taking the time to help educate a novice.
