The Spyderco Delica 4 Emerson Folding Knife combines all that's
functional and performance-based in a Spyderco folder with the
blade-opening feature made popular and patented by Ernest Emerson of
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.
The gray fiberglass reinforced nylon handles are molded with
Bi-Directional Texturing for traction and improved ergonomics. Inside
the handle dual skeletonized stainless steel liners strengthen the knife
without additional weight and create an anchor for external and
internal components to attach through for more sturdiness and rigidity.
Their VG-10 blades are flat saber-ground with a stronger tip and 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.
