You are welcome Truck.
I had a feeling this was going to be stainless. The blades just stuck out as not the same as other Rangers. Too shiny and clean. Colonial used 420 for most of their stainless knives. They also used some 440 but it was reserved for what they considered their higher end knives. I do believe its most likely this knife was made with 420.
I have seen Colonials pine knot knives before but I have never seen this truck driver model.
With your name I think this one was meant to be yours. Very cool thanks for sharing it with us.
