The Spyderco Delica 4 Lightweight Blue is a masterclass in practical design, everyday reliability, and comfort-driven performance. If you’re after a knife that combines premium materials, thoughtful ergonomics, and proven Spyderco engineering in a compact, lightweight form, the Delica 4 delivers all that and more. It’s one of the most trusted folding knives on the market, and once it’s in your hand, you’ll see exactly why.
The 2.9” plain edge blade is made from VG-10 stainless steel—one of the finest steels available for everyday use. It offers an excellent balance of edge retention, corrosion resistance, and easy sharpening, making it ideal for users who rely on their knife throughout the day. The satin finish not only adds a refined touch but also reduces reflectivity while helping resist wear over time. Its clip point profile is perfect for detailed slicing, precise cuts, and general utility work.
Spyderco’s iconic round thumb hole gives you smooth, one-handed deployment, even when you’re wearing gloves or dealing with wet conditions. Once open, the blade locks up securely thanks to the tried-and-true backlock mechanism. This system has stood the test of time for its strength and dependability, giving you confidence in every cut.
The handle is where the Delica 4 truly shines. Made from lightweight blue FRN (fiberglass-reinforced nylon), it offers excellent durability while keeping the knife’s total weight down to just 2.4 ounces. The Bi-Directional Texturing molded into the handle ensures a secure grip in any condition—wet, dry, hot, or cold. It's built for comfort and control, with subtle contouring and just the right amount of tactile feedback to stay put in your hand without being overly aggressive in your pocket.
Versatility is a major strength here. The four-position pocket clip allows for tip-up or tip-down carry on either side, making it fully ambidextrous and ideal for left- and right-handed users alike. The clip is secure and low-profile, keeping the knife accessible without drawing attention. Add a lanyard hole, and you’ve got even more carry options.
When closed, the knife measures just 4.25”, making it incredibly pocket-friendly. Fully deployed, it stretches to a balanced 7.11”, giving you ample cutting power without being bulky or intimidating. The slim profile disappears into your pocket, but when it’s time to work, it performs with the confidence of a much larger blade.
The Delica 4 Lightweight Blue is the kind of tool you’ll reach for again and again. Whether it’s opening packages, cutting rope, or tackling everyday tasks, it handles it all with ease and style. This is one of those knives that quickly becomes a favorite—not just for its performance, but for how naturally it fits into your routine.
