Their FRN (fiberglass reinforced nylon) handles come in new vibrant tones including blue, green, brown, gray and purple. Molded onto the handle's surface is Bi-Directional Texturing for slip-free tactile traction. Inside the handle are dual skeletonized stainless steel liners which strengthen the knife without additional weight and double as an anchor for external and internal components to attach through generating more sturdiness and rigidity.
