KA-BAR is a highly recognized brand to which many older adults are sentimentally attached even today. This is perhaps because the brand has the impression of going beyond social backgrounds and generations. Your grandfather may have a KA-BAR knife brought from WWII’s filthy trenches, or you may have one to treasure its reliability to protect yourself or others during a civil war.

Apart from its rich history, the brand has produced a variety of knives since its inception in 1897. Thus, identifying the exact manufacturing date of any KA-BAR knife requires you to know about its historical journey of over 120 years featuring hurdles and interesting chronicles regarding its different knives.

Alternatively, one could do these as well.

  • Looking for the Serial Number: A KA-BAR knife usually has a model or a serial number of two or four digits. You can then look up the number in an antique cutlery book or in the brand’s catalog to know the type and age of that specific knife.
  • Exploring the Print Items: These items include old catalogs, magazine ads, books dedicated to knives, and a brochure that may have come with your knife. These are reliable sources to know the age or manufacturing year range. This is because they typically will have images and other information. They are handy, especially when the knife in your hand is worn or broken. However, even the KA-BAR collectors feel it challenging to find the specific age of a knife by just glancing or examining it. Thus, they also refer to one or more print materials.
  • Looking on the Internet: There are a couple of forums and portals dedicated to vintage or commemorative knives, especially by collectors. These are also reliable to know about your knife’s age. You can even look for antique shops or local knife collectors to get the information you are looking for.
