Should the discrepancy in handle cover jigging, coarser on one side, finer on the other, seen below, raise a question about post-factory replacement? Or, is it likely that along with the black composition material being a substitute for the unavailable natural bone during the make-do WWII era, there was greater latitude in other respects in getting product out for the public?
Nothing else that I can see appears “off” about the knife.
The ROBESON SUREDGE equal end 632319 whittler I gather is not rare. At only $10 from an antique shop, I am happy to have acquired it, but am still curious about what we are seeing.
