No Tom, the only thing I did was replace the sheath with a Jim Buffaloe one, and paint the butt cap.
The FB you are refering to isnt mine, it might belong to a great guy called Johnathon, if it was number 7.
I now have the UC machete in a work bench display, with a screen accurate boat prop, arrow head, headband and real metal shavings from Gils workshop.
