Spyderco Delica 4 Folding Knife Review

Let’s Talk About Spyderco Delica 4 Folding Knife

The Spyderco Delica 4 Folding Knife is a legend in the EDC (Everyday Carry) world. Spyderco, a company known for its innovative designs and quality craftsmanship, introduced the Delica in 1990, revolutionizing the market with a lightweight, one-hand-opening, and affordable pocketknife. The current Delica 4, especially in its K390 steel variant, represents a culmination of years of refinement and a commitment to using premium materials, making it a compelling choice for knife enthusiasts and everyday users alike.

For years, I’d been searching for a dependable EDC knife that could withstand the rigors of daily use without weighing me down. I needed a blade that could handle everything from opening packages and cutting rope to more demanding tasks during camping or hiking trips. The Delica 4 kept popping up in conversations with other outdoor professionals, and its reputation for durability and sharpness piqued my interest.

Upon unboxing the Spyderco Delica 4 Folding Knife, I was immediately struck by its lightweight design and the textured feel of the FRN (Fiberglass-Reinforced Nylon) handle. It felt solid and well-built, despite its light weight. The blade’s leaf shape and the signature Spyderco opening hole were instantly recognizable.

I’ve used many pocketknives over the years, including the Benchmade Griptilian and the Ontario RAT Model 1. I chose the Delica 4 primarily for its size and weight. While the Griptilian is a great knife, it can feel bulky in the pocket. The RAT Model 1 is a solid budget option, but the steel isn’t in the same league as the K390 of the Delica 4.

My first impression was overwhelmingly positive. I was excited by the Spyderco Delica 4 Folding Knife‘s potential as a versatile and reliable EDC tool. The K390 steel promised exceptional edge retention and toughness, and the lightweight design made it perfect for carrying every day without feeling burdened.
