The earliest examples of these original survival weapons were made of minerals such as flint, which could be sharpened on both edges, as well as to a deadly point.

While carbon-14 dating cannot be used to date the knife itself, because it is metal and thus not a once living thing (steel does contain carbon, but this carbon may be from trees or coal and is not easily separated from the iron for testing).

However if the knife has a handle made of natural organic material (e.g, wood, bone, antler, ivory) this handle can be carbon-14 dated to obtain an estimate of the age of the knife.

Among many methods, carbon dating is most commonly used to date fossils.

By learning the simple Case dating system, you can easily determine the year a Case knife was manufactured.

In 1970, Case added dots beneath the "USA" on the tangs of all knives. So, nine dots appeared in 1971, eight in 1972, and so on.

Carbon 14 dating techniques are only useful up to 60,000 years and therefore are mainly used by archaeologists and not very much by geologists.

First, a "Lightening S" appeared in both "CASE" and "USA." Secondly, the dots were placed above the "USA" From 1990 to mid-1993, the dot system was replaced with a stamping of the actual date.If folding knives and pocket knives were developed as tools, fixed-blade knives began their history squarely as weapons.Crude stone blades were carried by Neolithic hunters who, we might guess, were anxious to subdue their prey before being preyed upon themselves.Carbon dating is a method of telling approximately how old an ancient object is. The scientists used carbon dating and decided that the mummy was 10,000 years old. In carbon dating, the approximate time taken by the item to degrade to half is calculated according to the degrading time of carbon which is nearly constant.Carbon dating is not perfect, but it can give you a rough idea. In this way half of this half portion is calculated and the process goes on till we dont find the exact age of the item.
