Spyderco: Delica 4 - Emerson Wave - Blue Gray FRN - VG-10 - C11PGYW
This is one of the best-selling knives Spyderco makes. The latest generation has FRN (fiberglass reinforced nylon) handles with 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.
The blades are full flat-ground VG-10 with a thinner highly refined cutting edge and a larger 13mm opening hole. Added to the blade's spine is slip resistant jimping. Phosphor bronze washers smooth out the open/close action, and the clip is upgraded to a four-way tip-up, tip-down, left-or right-handed clip.
The Emerson opening feature is a hook curving out the top of the knife's blade. When removing the knife from a front pocket it catches the pocket's edge quickly opening the knife blade ready to use. The knife can also be taken out of the pocket without engaging the opening feature by pulling it straight up and out with your fingers on top of the closed blade.
