What Is Epoxy?

Epoxy is a strong adhesive system made of two parts.

Both parts are a liquid that is mixed together. Usually, one part of A to one part of B. Read the directions and follow them to mix up your epoxy.

As a liquid, epoxy can be used as a coating, laminate, and infuse materials like wood and carbon. It provides waterproofing, strength, and endurance.

When it cures, dries, or hardens, it becomes a resin. The resin provides a range of benefits.

Other times, there are additives stirred in with the epoxy, and you can use it like glue, filler, or a wide range of other purposes. In fact, different epoxy resins have been developed over some time for specific and specialist uses. One such specific use is marine use.

What Makes West System G/Flex Stand Out?

 Several things make West System G/Flex stand out. Some of which are:

  • It is a bit more pliable than regular epoxies, but it is also much firmer than paste sealants.  
  • Creates physical connections that can absorb the strain of spreading, shrinkage, shock, and trembling.
  • Provides excellent bonding of dissimilar materials
  • It has 150,000 PSI of elasticity that sticks steadfastly to metals, plastics, glass, stonework, and fiberglass.

Now we know what makes it stand out, what makes it the best epoxy for knife handles? One is how it bonds to metals, plastics, and wood—two; you can use it on moist or damp surfaces and even underwater.

The fact that it can handle water means that it will stand up to multiple washings by hand with dish soap and water. Chances are it will be fine in a dishwasher, too; but, knives really should be washed by hand. The dishwasher can dull the knife blades from the water’s force, bouncing them around against other silverware and the dishwasher’s flatware basket.

G/Flex Epoxy Vs Other Glues

Compared to wood glue, G/Flex does a much better job of adhering to materials, especially wood. It has a high bonding power you can’t get from other products on a wide array of materials.

Epoxy for knife Handle

G/Flex seeps down into the cracks and grain of the wood. Wood glue will, too but only to a point, thereby making G/Flex epoxy the better choice.

Because it seeps down into the material, it gives it more strength in adhesion. That strength makes it last longer. It fills in gaps between the pieces you put together, making them water-tight. That means water cannot cause rust, swelling, cracking, and other issues.

Superglue works well on certain products, but G/Flex works best on all types of products. For example, wood and metal, metal and plastic, etc., superglue does not adhere to specific material types.

Having tested the three mediums for knife handles, G/Flex does a much job than wood glue or super glue at adhering the handle to the knife. It does a better job at repairing a crack or chip as well.

What Users Are Saying

People who use this product find it has amazing bond power.

 Customers have used it to fix a vast array of items, from skis to attaching knife scales to handles.

 Many people have used this item for fixing different products and different materials, including fiberglass, vinyl, glass, and more. All have been extremely satisfied with the results of G/Flex epoxy. Now imagine what kind of results it will give you for knife handles.
