Your right Bob...ALL knives I have ever seen by him are tricked out in some way....
saw a knifemaker a year or so ago at the big Wolverine Knife Club / Michigan Antique Arms knife show
with 3-4 different knives but all made with same blade like yours
Said they were genuine DY blades, but he made em them into knives
Also, in the last 5 yrs, I have bought the wife 4-5 pieces of Navajo made goodies.. as sometimes
on my way to winter camp in Arizona, I go right thru the middle north to south of the rez
I go thru right after Labor Day, and run up on a lot of roadside venders
A Navajo fella had 3 knives he made and said the blades were DY, he made the knives himself
That Rez is huge !!! Sets up in the NE corner of Arizona
Bet there is one fact a lot of folk's do not know, unless you have drove across and realize how big
the Navajo Rez is.....bigger than 10 of the 50 US states, including West Virginia !!!
