G10 is a recent addition to the synthetic or man-made handle material group. G-10 is a glass (fiberglass) reinforced epoxy,
and it is a very tough, hard, and durable handle material. Because it has fiberglass linen as reinforcement, it is physically
stronger (more break resistant) than Micarta phenolic. It is scientifically manufactured, and the epoxy used is a specialized
industrial grade which has heat resistance properties. It's also made with electrical grade, non-alkali glass cloth, and formed
and catalyzed under heat and pressure.  It's waterproof, a little harder and slightly more brittle than Micarta, and has a more
profound pattern when ground and finished, which is probably its greatest appeal. You'll notice in the photos below that the
layered patterns vary in density and number of layers exposed in the curves of a knife. This is because different runs of the
material have different layer numbers and thicknesses.

Like phenolics, G-10 that has been bead blasted will darken with the oils of human hands, but can be restored by a cleaning
with denatured alcohol, lacquer thinner (use carefully and sparingly) or even brake cleaner aerosol spray. A denser appearance
with more vibrant color can be achieved after cleaning with a light coating of WD-40, wiped off.
