Class characteristic - properties of evidence that can only be associated with a group and not a single source.
> Measurable features of an item that indicate a restricted group source based on design factors determined prior to manufacture.
> May be shown to be like or consistent with a questioned source, although not uniquely identifiable with that source.
Examples:
> A pair of faded blue denim jeans with paint stains and possible matching cuff.
> A pair of "NEW" and "UNUSED" Nike Air Force II shoes size 10 found in a crime scene (it won't help us distinguish it from other Nike Air Force II athletic shoes of the same size).
> Width of the tip of a screwdriver
> Width of land and groove impressions
=============================
Individual characteristics - properties of evidence that can be attributed to a common source with a high degree of certainty.
> Marks on an object produced by the random imperfections or irregularities on the surfaces of the tools used to manufacture the object.
> Produced incidental to the manufacturing process and typically seen at microscopic level.
> Can be produced on an object by use, abuse, and/or corrosion.
> May be uniquely identifiable with a source.
Examples:
> Fingerprints - the odds of two people having the same prints are one out of 1 x 10 to the 60th power. This is greater than the known number of humans on the earth.
> Bullet striations from gun barrels, tool marks, bite marks and irregular edges that fit together like a jigsaw puzzle.
> Striated and/or impressed marks produced by the action of the tip of a screwdriver on an object.

Class evidence is common to a group of objects or persons, while individual evidence can be linked to a unique source. Class evidence can help narrow down a pool of suspects, while individual evidence can provide a stronger link to a specific person or object. Class evidence is less specific and can be shared among multiple sources, while individual evidence is more specific and can help to identify a singular source.
Class evidence is the category for most evidence. Class evidence is evidence associated with a group and not a single source. Example: general piece of something (like a paint chip) blood (we can only generalize) Individual evidence is evidence that can be virtually, unambiguously traced to a source. Example: finger prints DNA tool marks (under a microscope) anything torn or broken (must be very specific)
The difference between the Class 365 and Class 465, 466 is basically the cost.

Fibers are CLASS evidence. They cannot be individualized to a single person or thing, although there are many types of natural and synthetic fibers.
