What is G10


G10 is a composite material made of epoxy resin and glass fiber, specifically a glass-based epoxy resin laminate. It consists of multiple layers of glass cloth, which are saturated with epoxy resin and then cured under high pressure and temperature. The resulting material is durable, lightweight, and moisture-resistant, making it an ideal choice for knife handles.


G-10 has its roots in industrial laminates, which were first developed by George Westinghouse in the early 20th century. Westinghouse initially used phenolic formaldehyde resins as the base for these laminates, but later advancements in material science led to the development of epoxy resins and their incorporation into composite materials. The glass fibers used in G-10 offered a significant improvement over carbon fibers, providing greater strength and resistance to wear.


The properties of G10 make it a popular choice for knife handles and other applications where durability, strength, and moisture resistance are crucial. Some of its key properties include:

  • High tensile strength: The combination of glass fiber and epoxy resin creates a material with excellent tensile strength, which helps knife handles withstand heavy use without breaking or deforming.
  • Dimensional stability: G10 remains stable under a wide range of temperatures (-196℃ to 300℃) and does not shrink or swell, ensuring that the knife handle maintains its shape and size over time 1.
  • Moisture resistance: The epoxy resin in G10 acts as a barrier to moisture, making the material resistant to water absorption and humidity.
  • Chemical resistance: G10 is resistant to many chemicals, including acids and solvents, which protects the knife handle from damage caused by exposure to harsh substances.
  • Lightweight: Although G10 is strong and durable, it is also relatively lightweight, making it suitable for use in knife handles without adding unnecessary bulk.

Knife Handle Materials Comparison

When it comes to knife handles, the choice of material can greatly affect the overall performance, durability, and aesthetic appeal of the finished product. This section will explore different knife handle materials and compare their properties, advantages, and disadvantages.

Other Composite Materials

G10 is a popular composite material used for knife handles, known for its strength, durability, and water resistance. G10 is a type of fiberglass laminate made from layers of glass cloth, soaked in epoxy resin, and cured under pressure. Its qualities make it an excellent option for demanding applications such as tactical and kitchen knives.

Micarta is another composite material commonly used for knife handles. It is made from layers of paper, canvas, or linen soaked in phenolic resin, which are then pressed and cured. Compared to G10, Micarta provides a slightly softer and warmer feel, with more natural colors and patterns available. However, it is less resistant to water and may require more maintenance.

Carbon fiber is a premium choice for knife handles, prized for its light weight, high strength, and sleek appearance. It is made from carbon fibers bound together by a resin, cured under high pressure and temperature. While offering impressive strength-to-weight ratio, carbon fiber can be more expensive than G10 and Micarta and may be more prone to chipping or cracking under extreme stress.

Natural Materials

Wood is a traditional material used for knife handles, valued for its beauty, warmth, and ease of shaping. Many wood types are available, ranging from inexpensive domestic wood like maple or walnut to exotic burl wood with intricate grain patterns. Wood handles can be comfortable to hold and offer a timeless aesthetic. However, they are generally less rugged, require more care, and may be susceptible to moisture damage compared to composite materials.

Bone, often used in historical or ornamental knives, provides an organic look and feel that is difficult to replicate with other materials. Bone handles vary in color and pattern, and can even be carved or embellished for an extra touch of elegance. Like wood, bone requires more maintenance to protect it from drying out or cracking, and may not be as strong or water-resistant as G10, Micarta, or carbon fiber.

In summary, when choosing a knife handle material, it is important to consider factors such as the intended use, desired appearance, and maintenance requirements. While G10, Micarta, and carbon fiber provide impressive strength, durability, and water resistance, natural materials like wood and bone offer a warm, comfortable feel and timeless beauty. Ultimately, the choice of material will largely come down to personal preference and what best fits the user’s needs.
