I have a folding,locking,camillus machete that is made just like the case folding machete's I have seen at knife shows.The guy I got it from said it is WWII era.Can anyone tell me about how old it is,how many were made,ect.,The condition is nice.The edge looks factory with one small dent.It has the usual old age cosmetic discoloration.It even still has the removable edge guard! THANKS!!!!!
