White Tail Cutlery was mentioned in a recent thread (on this forum, or some other?) that was originally about McGrew Knives. The tie-in was that both brands could be bought in perpetual yard sales in Arkansas.
I have a knife with "White Tail Cutlery Handmade" printed on the blade. I always thought that it was a one-guy-in-his-garage low budget sort of thing, made just to supply Arkansas junk shops.
After doing some brief online research into White Tail Cutlery, I'm still unsure about the knife I have. There is an importer of knives from Pakistan that uses the name White Tail Cutlery. And I found online some documents relating to a court case involving the name - it seems that someone left the company and began importing their line of White Tail Cutlery from Pakistan too. The second company was being sued to stop. They argued that the term "White Tail Kinfe" was generic and anyone could say their knife was a White Tail - the court disagreed.
So it's probable that my knife is from one of those two sources. However, it doesn't have a "Made In" stamp, so the one-man-garage-made theory isn't eliminated either.
Based on the quality of my knife, I'd say a similar knife with stag handles would be worth $10, mainly because of the stag. I think I paid $5 for mine over a decade ago. The wood handles look nice and the spring is very strong. But the cheap blade printing is nearly invisible, the brass liners aren't straight, and there's side-to-side blade movement even though the knife has never been used. There's a crude medallion on the side of the handle with a deer head that appears to have been banged into place, as though the circular notch wasn't the proper size.
The quality of mine is similar to Pakistani knives, but I would expect a "Made In" stamp if it were.
