Micarta : Knife Making Material

Micarta : Knife Making Material

While Micarta is a common material used in knife manufacturing, you may be unfamiliar with micarta knife handles or micarta knife scales. Micarta is another resin-based material that is classified as a composite. Micarta, like compressed and laminated glass, is composed mainly of burlap, linen, or canvas. The laminate layers are adhered together with phenolic resin and then crushed with heat to form a durable material widely used in various kitchen knives.

 

What exactly is Micarta?

Micarta is a trademark for a range of composite materials. On the other hand, Micarta has developed into a generic word, similar to Kleenex or Coke.

Micarta is a fabric-resin composite material. It is created by soaking layers of linen, canvas, paper, or textile material in resin and squeezing them together. Micarta may be made from a variety of various resins and fibers.

Micarta may be used for a variety of things besides knife handles and micarta knife scales. Countertops, propeller blades, hard helmets, and various other durable goods are made from the composite.

 

Why is Micarta knife handles so popular?

Micarta is robust, and it withstands severe usage for an extended period. Micarta handles and scales maintain their form exceptionally well.

However, with Micarta, great strength does not always imply hefty weight. Despite its great strength, it remains a relatively lightweight material. Despite being waterproof, Micarta's texture doesn't alter much when wet. This improves grip in damp or rainy situations.

Additionally, it is visually appealing. It has a beautiful appearance and a nice texture that feels great in hand.

Another reason it's such a popular material for knife handles is that it's simple to mold and personalizes. Micarta is available in an array of colors, textures, forms, and sizes.

 

Are Micarta Knife Handles Waterproof?

Micarta is capable of absorbing a small amount of water, liquids, and moisture. This is because the weave used to create the laminated material may include holes at the borders or gaps in areas where the phenolic resin did not fill the space, even if water penetration is minimal. Additionally, Micarta's somewhat pliable surface may acquire dents, scratches, and open spots that enable water to penetrate.

 

How Long Does Micarta Kitchen Knife Handle Last?

Micarta provides long-lasting kitchen knife handles that work well for many years of dependable usage. Micarta knife handles are made of a variety of materials, including linens, paper, and canvas. While the majority of micarta handles are composed of linen, several also include paper and canvas.

 

How To Create Micarta Knife Handle

 Due to the rough nature of the material, it is ideal for knife handles and handles scales. Micarta has rapidly become one of the most often used handle materials on modern knives. Due to its gripping texture and broad color choices, it is seen on bushcraft, tactical, and daily carry blades. We decided to try our hand at creating Micarta for this post.

There are many methods for making Micarta, but they all have a few characteristics. Micarta is made using three components: resin/epoxy, material, and pressure.

The following is a list of the materials that we employ to create our Micarta. While these are not all things, you will need, having the appropriate supplies may make all the difference.

  • Jeweler's Epoxy or Fiberglass Resin

  • 2x4 Wood for the construction of your shape.

  • MDF or particleboard (3/4" recommended thickness)

  • Screws Made of Wood

  • Clear Tape for Packing

  • Extra-Large C-Clamps

  • A Cup for Mixing

  • Sticks for Mixing

  • A Spatula or Putty Knife

  • Porous Cloth, Canvas, and Denim, among others.

  • Protective eyewear, gloves, and a mask/respirator

Note: Combining epoxy and resin may be hazardous to your health. Wear the required personal protective equipment and work in a well-ventilated location to create your Micarta.

STEP 1: PREPARATION OF MATERIALS AND CREATION OF THE MOLD

Micarta production is a relatively quick yet accurate procedure. It entails developing a strategy, preparing your materials, and working as quickly as the resin/epoxy can set. We utilized our 2x4 wood screws, packaging tape, and MDF to create a mold for our Micarta. The 2x4 functioned as the mold's frame, while the MDF performed as the bottom lid and push. We lined the interior of the mold with packing tape to aid in the release of the Micarta after the resin had set. After that, we cut our denim into squares that would fit comfortably within the form and put them away for later use.

STEP 2: COMBINE THE RESIN

Use the plastic mixing cup to measure and blend your resin. We used eight oz resin and 80 drops of hardener for our Micarta, following the directions on the resin bottle. These quantities will vary according to the kind of resin/epoxy used. The amount we used was sufficient to soak our denim thoroughly, but it was preferable to have too much resin than not enough. Micarta must be layered approximately 10 minutes after the resin is hardened using the hardening agent.

 

STEP 3: MATERIALS FOR THE LAYER

Begin by putting a 1.5" drop of resin into the form's bottom and covering it with a piece of cloth (or other material). Pour more resin on the fabric and distribute and saturate it using the putty knife or spatula. Once that layer is soaked, continue with another layer of cloth and additional resin.

Carry on in this manner until the required thickness is reached. Increase material for thicker handle scales, or vice versa.

STEP 4: INCREASE THE PRESSURE

After stacking our materials, the following step is to apply pressure. We took an MDF cut to fit the shape we created and pressed it with some big C-Clamps to make the Micarta. It is essential to choose a sufficiently thick and robust piece to apply equal pressure to the materials.

STEP 5: EXERCISE PATIENCE

This stage is more straightforward for some than for others. For at least a day and a half, resist the temptation to break up your form. Time is required for the resin to solidify and cure completely throughout the micarta block.

STEP 6: REMOVE MICARTA FROM THE MOLD

This is a very straightforward process. Unclamp the c-clamps and remove the Micarta from the mold. Ideally, the block will be uniform in thickness. You may now break it into smaller pieces, fashion handle scales from it, or use it as a paperweight, among other things. To create the rough texture seen on our preferred manufacturers' production micarta, just sand away the top layers of resin until you reach a matte finish.

 

Conclusion

Making Micarta for the first time may be a bit of a learning experience for some people. Based on the conditions used to create it, the quantity of resin used and the curing period will vary. We recommend testing new materials in small batches and making necessary changes. Micarta is simple to manufacture at home and does not need any special equipment. If you wanted to make Micarta even easier, you could stack your materials between two boards and then top them with a couple of cinder blocks or other heavy items.
