What is Micarta and how to use it to make knive handles

Micarta is commonly used for knife handles, countertops, and electrical insulators, among other applications. Micarta is known for its durability, resistance to moisture, and its ability to be easily shaped and polished. It’s available in various colors and patterns, depending on the type of fabric and resin used. Let’s understand the properties of Micarta for knife making. What are the most popular types of Micarta for knife handles?

What is Micarta?

Micarta is a material made up of a polymer film (based on synthetic resin) bonded with various papers, fabrics, or other similar structured materials. By appropriately selecting the color of the base material and the binding resin, various color compositions can be achieved. Micarta feels warm to the touch and does not slip in the hand. The three main types of Micarta are linen (linen cloth, fine weave), canvas (various fabrics with a coarse weave), and paper.

Micarta is a modern, innovative material that possesses qualities superior to wood and regular plastic. It does not interact with water, does not absorb food odors, has a good appearance, is easy to work with, durable, and comes in various colors, from solid to multicolored. Due to these qualities, Micarta has become widely popular as a material for knife handles. Its safety is confirmed by the FDA (U.S. Food and Drug Administration).

What is the difference between a Micarta and a G10?

G10, on the other hand, is essentially the same as Micarta, but instead of linen or other natural fibrous materials, it uses fiberglass. Both Micarta and G10 are actually what’s known as phenolic laminates, so in that sense, they are the same. However, the primary distinction between the two is the type of fiber used in the laminate. G10’s use of fiberglass often makes it slightly tougher and more resistant to moisture and chemicals than Micarta, but the choice between the two often comes down to personal preference, aesthetics, and specific application needs.

What is Norplex Micarta?

Norplex Micarta is a company responsible for many of the resin-based handle materials we see on knives today. Over the years, it has become so renowned that it can be dubbed the “big boss” in the world of resin materials.

Micarta is a registered trade name and is a type of phenolic. Typically, when we say “Micarta,” we’re not just referring to any kind of resin composite. There’s a reason we differentiate by saying G-10 handles and then Micarta handles. The name “Micarta” has become synonymous with high-quality resin-based materials, largely due to the reputation and quality standards set by Norplex Micarta. The company has set a benchmark in the industry, and its name has become a byword for quality in this specific niche.

Where can I buy Micarta?

Micarta can be purchased from various suppliers, both online and in physical stores. Here’s where you can generally find Micarta:

  • Online Retailers: Websites like Amazon, eBay, and specialized knife-making supply stores often carry Micarta slabs and scales in various thicknesses.
  • Specialized Knife Supply Stores: Stores like Jantz Supply, KnifeKits, and Texas Knifemaker’s Supply are popular destinations for knife-making materials, including Micarta.
  • Local Hardware Stores: While not as common, some larger hardware stores might carry Micarta or can direct you to a local supplier.

Average Cost: The price of Micarta can vary based on the type, color, and size. Average cost for a set of Micarta scales (for knife handles) can range from $10 to $50 or more, depending on the quality, type, and size. Slabs might be more expensive, especially if they are larger or thicker.

For example, Micarta available in slabs and scales with thicknesses including 1-1/8”, 1/4”, 1/8”, 3/16”, 3/8”, and more at Jantz.

Popular Types of Micarta

  • Canvas Micarta: This is one of the most popular types, known for its rugged appearance and excellent grip, even when wet.
  • Linen Micarta: Offers a finer texture than canvas and is often chosen for its aesthetic appeal.
  • Paper Micarta: Has a very smooth finish and is often used for applications where a more polished appearance is desired.

When purchasing, always check the product description to ensure you’re getting the right type and thickness you need for your project. If you’re new to working with Micarta, it might also be helpful to read reviews or consult forums to get recommendations on the best types and suppliers for your specific needs.

DIY Micarta

Micarta typically means that the handle has a base material of linen, canvas, or paper. However, this term encompasses a wide range of materials, including wood and denim fabric. Most often on production knives, you’ll see canvas and linen, or perhaps some combination of materials layered together.

If you’ve ever delved into DIY projects of this nature, you’ve likely come across a plethora of “DIY Micarta handle scales” videos. Most of these will give you a good idea of the process: strips of fabric are soaked in resin, then placed in a mold and compressed with clamps until they dry.

Once the resin has cured, you’re left with a slab of Micarta that can be sanded down to the state of knife handle scales. This is a simplified version of what typically happens on an industrial level, but it gives you a good idea of its versatility.

Depending on the material used, various stylistic choices can be made, from coloring the resin used to soak the layers to the type of mold used. And since all of this can be purchased at any hardware store, it’s relatively easy to do on your own.
