G10, 3-0G10 is a material that is often used in cutlery for the construction of handles as an alternative to Woodto Bones and hornsper Micarta, carbon fibre, Juma, etc. due to its advantageous characteristics of the material and the economical price but which provides the handle of the knife that requires practically no maintenance.

G10 in cutlery is a widely used material especially in the market and among American makers.

Used both for the plates for the handle, to create colored spacers, as an alternative to vulcanized fiber, which I personally prefer for a warmer and more natural effect.

The G10 is composed of layers of woven fiberglass impregnated with epoxy resin. The layers are stacked together and then cured at high pressure and temperature to form a solid and durable material.

G-10 material is favored for its high strength, low moisture absorption and high level of electrical insulation and chemical resistance.

These properties are maintained not only at room temperature but also in humid conditions for these is often used on EDC knives, survival knives, etc.

It was first used as a substrate for printed circuit boards and its designation, G-10, derives from a national electrical manufacturers association standard for this purpose.

The decorative variations of the G-10 are produced in many colors and patterns and are mainly used to make knife handles, gun grips and other tools.

These can be textured (for grip), shot peened, polished or polished.

Its strength and low density also make it useful for other types of crafts.

They are produced in laminated plates of various sizes, thicknesses and colors of all kinds.

What material is the G10?

G10 is sometimes called Garolite is a resin-based composite , it is a high-pressure fiberglass laminate, a type of composite material.
The material is made from sheets of fiberglass that are pressed together using an epoxy resin.
It is created by stacking multiple layers of glass fabric, soaked in epoxy resin, then compressing the resulting material under heat until the epoxy resin hardens.
It is produced in flat plates, most often a few millimeters thick.

The G-10 is very similar to the Micarta and carbon fibre laminates, except that: Glass fabric is used as a filler. (Note that the professional nomenclature of “filler” and “matrix” in composite materials can be somewhat counterintuitive when applied to soaking fabrics with resin.)

G-10 is the most durable of fiberglass resin laminates and therefore the most commonly used also for the creation of knife handles.

These key points highlight the remarkable characteristics and applications of the G10 material.

Its high strength, electrical insulation capacity, chemical resistance and temperature stability make it a versatile choice in sectors ranging from electrical engineering to aerospace and beyond as in the case of both industrial and artisanal cutlery.

Dangers and Safety in working the G10

G-10 is safe to work with but with the right attention.

G10 is a material composed of resin and glass fibers, and is considered generally safe for human use.

It does not contain significant toxic substances and does not emit harmful gases under normal conditions of use.

Dangers can arise from cutting or grinding the material, as glass and epoxy dust are known to contribute to respiratory disorders and may increase the risk of developing lung disease.

For any such work, the workspace must be properly ventilated, and masks or respirators must be worn.

Also remember that epoxy resin is flammable and, once ignited, will burn vigorously, emitting poisonous gases.

For this reason, materials such as FR-4 containing flame retardant additives have replaced G-10 in some applications.

As with any material, it is important to take appropriate precautions when processing.

When G10 is cut or shaped, dust particles can be produced that can irritate the eyes, skin or airways.

Therefore, it is advisable to use personal protective equipment, such as goggles, gloves and masks, when working with the G10 to avoid inhalation or direct contact with dust.

In general, if G10 is used as a knife handle and is not ingested or handled inappropriately, there should be no significant risk to human health.

Conclusions

Personally I use the G10 on a low percentage of knives because I prefer micarta as synthetic materials.

When I use the G10 I look for colors with mixed textures or in any case particular, otherwise I find the micarta vs G10 warmer as a material for a knife.

The G10 offers a combination of mechanical strength, corrosion resistance, secure grip and chemical resistance that make it a good material for cutlery.
