The DAK Centurion is not very special. It was handed to the soldiers only for a short time when supply ran out of the standard Vic.
However the Centurion came with a special black pouch, not the standard DPM one.
In the picture left is the standard pouch and knife. Right is the pouch fort he Centurion. It has a different Nato Stock Number. The pouch is much more rarer than the knife!
BTW: The logo on the green knife is called the ‘Intercervice logo’. It consists of a lion (Army), an anchor (Navy) and a bird (Air Force).
