Yes thats right they normally are not numbered but Schrade
prototypes are often numbered when the subsequent preceeding
full production models of the same version or type are not. I have
found this to be true with a number of different Schrade prototypes
and their subsequent versions of same so I dont doubt it is true. I
cant say how often this occurs.
Perhaps it is stainless ? Here below is the same knife compaired with
a knife that is definitely a stainless 153 UH, there are a number
of unaccounted for differences highlighted. I pressumed that
these differences were because the other was a carbon steel knife?
Ignore the green dots.
