If you already own a Delica or Endura, you have one of signature knives Spyderco makes. They are now available in a range of new handle colors with full-flat ground blades. 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.
