I am a long time Randall Knife collector.
Facebook has 4 groups dedicated to Randall knives and that is where you will get your best price and model information.
Start with the website Randall Knives and look at the current catalog prices for knives.
You can order those knives directly from the Shop and wait 6 years for delivery, or go to an authorized Randall Knife dealer and receive it in about 7 to 9 months.
Colorado's dealer is Spyderco, but they don't take custom orders.
The dealers have been cut back by thirty five percent for their orders, so they pretty much won't order the lower priced knives. They have increased in value due to that.
Resale is best on Facebook, second best on Ebay.
If you don't want to do Facebook, send me pictures, and I can give you a ballpark values, and may be a buyer depending on condition.
If the Randall is collectible, the name does not matter.
