The Spyderco Delica debuted in 1990 alongside its bigger brother, the Endura, and together they were the first lightweight, clip carried, one hand opening folders most people could actually afford. Four generations of Constant Quality Improvement later, the Delica 4 is still one of Spyderco's best sellers worldwide. It is built in Seki City, Japan, and our Spyderco history covers how the pair changed who could carry a real folder.
The Delica 4 runs a 2.875 inch VG-10 blade with a full flat grind at .093 inch stock, thin enough to slice cardboard, packaging, rope, and food with almost no drag. A 13mm Round Hole opens it with either hand. The FRN handle carries Bi-Directional Texture for grip wet or dry, with skeletonized steel liners for rigidity. It measures 7.125 inches open, 4.25 closed, and weighs 2.5 ounces.
A refined back lock sits on the spine, so a press of the rocker releases the blade, and it has proven itself across millions of Delicas. The four position clip carries tip up or tip down on either side. Our guide to knife lock types explains why the back lock has lasted.
VG-10 is the standard, and sprint runs and exclusives step up to K390, Cru-Wear, and SPY27, plus Damascus with titanium scales and carbon fiber builds. Our comparison of every major knife steel shows what each upgrade buys you.
Beyond the color lineup, the Delica comes in plain, partially serrated, and fully serrated edges, a Wharncliffe blade, a Wave opening version that deploys on the draw, stainless steel handles, a trainer, and a knife kit. If you want more blade on the same platform, the Endura is the full size choice, and the rest of the Spyderco catalog is one click away.
