Spyderco Delica 4 Review: Is This The Best EDC Knife Under $100?
In the automotive world, the Toyota Corolla is the standard for reliability. In the watch world, it might be the Casio G-Shock. In the world of Everyday Carry (EDC) knives, that title undoubtedly belongs to the Spyderco Delica 4.
First introduced in 1990, the Delica has evolved through four major iterations to become what many consider the “perfect” EDC knife. It isn’t trying to be a tactical weapon or a flashy piece of pocket jewelry. It is, simply put, a cutting tool designed for human hands.
But in a market now flooded with ball-bearing flippers and powder metallurgy super-steels, can a lightweight lock-back knife from the old guard still compete? In this review, we revisit the legend to see if the Spyderco Delica 4 still deserves a spot in your rotation.

The Delica 4 hits a “Goldilocks” zone for size. It is large enough to handle 90% of daily tasks but small enough not to alarm coworkers in an office setting. It fits perfectly between the tiny keychain knives and larger tactical folders.

VG-10 Steel & Blade Shape
The standard Delica 4 utilizes VG-10 stainless steel, manufactured in Seki City, Japan. While steel snobs might turn their noses up at VG-10 in favor of MagnaCut or M390, VG-10 remains a fantastic choice for general utility.
Performance
VG-10 takes a razor-sharp edge with very little effort. It is highly corrosion-resistant, making it a great companion for food prep or humid environments. Its edge retention is decent—it won’t hold an edge forever, but it is incredibly easy to touch up in the field.
To understand where VG-10 sits in the hierarchy, check our guide on stainless steel vs. carbon steel. VG-10 offers a great balance of stainless properties without being impossible to sharpen.
Geometry
The blade features a full flat grind (FFG) on most modern models, which makes it an exceptional slicer. The spine includes a “hump” with jimping (texture) that provides a perfect resting spot for your thumb, offering immense control over the tip.
FRN Handle & Ergonomics
The handle is made of FRN (Fiberglass Reinforced Nylon). Yes, it is plastic. No, it is not “cheap.” FRN is virtually indestructible, resistant to heat, cold, and chemicals.
Bi-Directional Texturing
Spyderco uses a patented “Bi-Directional Texturing” pattern on the handle. The scales feel like they are gripping your hand back. Even if your hands are covered in oil, mud, or water, this knife will not slip.
Underneath the FRN scales are skeletonized stainless steel liners. These add rigidity and weight balance without making the knife heavy. It feels solid, not hollow.
The Bi-Directional Grip ensures you never drop your knife, even in wet conditions.

The Delica 4 uses a traditional mid-back lock. While it lacks the fidget-friendly speed of the AXIS lock found on Benchmade knives, it makes up for it in pure reliability.
The lock engages with a satisfying “thwack.” It is self-adjusting for wear, meaning the lockup will remain tight for decades. Spyderco also includes a “Boye Dent”—a small cutout in the lock bar lever—which prevents you from accidentally disengaging the lock while gripping the handle tightly.
Pocket Profile & Weight
At just 2.5 ounces, the Delica 4 disappears in the pocket. It is slim, smooth, and won’t weigh down gym shorts or dress slacks.
The pocket clip is a masterpiece of versatility. It can be mounted in four positions: tip-up, tip-down, left-side, or right-side. This makes the Delica 4 fully ambidextrous, a feature often overlooked in modern frame-lock knives.
It’s worth noting that for specific tasks, you might need different tools. See our breakdown of types of knives and their uses to see how the Delica fits as a generalist EDC compared to specialized tools.
Delica 4 vs. The Competition
Spyderco Delica 4 vs. Benchmade Mini Griptilian
The Mini Griptilian is the Delica’s closest rival. The Mini Grip has the faster AXIS lock and usually comes in S30V steel (better edge retention). However, the Delica slices better due to its thinner blade stock and offers better ergonomics for varied grip styles.
Spyderco Delica 4 vs. Spyderco Para 3 Lightweight
The Para 3 Lightweight is the “modern” Delica. It features the compression lock and better steel options. However, the Delica has a slimmer footprint in the pocket and a slightly longer cutting edge relative to its handle size. The Delica is also generally cheaper.

Frequently Asked Questions
Is the Spyderco Delica 4 worth the money?
Yes. While prices have risen to around $85-$95, the quality control, warranty, and sheer utility of the design make it a worthwhile investment that will last for years.
Is the Delica 4 legal to carry?
With a blade length under 3 inches (2.88″), the Delica 4 is legal in most US jurisdictions. However, because it locks, it is restricted in places like the UK. Always check local laws.
Can I close the Delica 4 with one hand?
Yes. It requires a specific technique where you depress the lock bar and let the blade fall onto your index finger (the unsharpened choil hits your finger), then you adjust your grip to close it. It takes practice but is easy once mastered.
Does VG-10 steel rust?
VG-10 is very corrosion resistant, but no steel is rust-proof. If you use it in saltwater, rinse it with fresh water and oil it. It is much lower maintenance than carbon steels.
What is the difference between the Delica 4 and Endura 4?
Size. The Delica is the smaller brother. The Endura 4 is significantly larger with a 3.75-inch blade. Choose the Delica for EDC and the Endura for heavy-duty work or self-defense roles.
Can I disassemble the Delica 4 for cleaning?
Yes, unlike the older pinned versions, the Delica 4 uses Torx screws construction, allowing you to take it apart for deep cleaning and maintenance.
Is the tip fragile?
The tip is fine and needle-like, designed for piercing and detail work (like removing splinters). It is not a screwdriver. If you pry with it, it will snap.
Does it come in other colors?
Yes! One of the best things about the Delica is the variety. You can get handles in Blue, Green, Grey, Purple, Orange, Black, and even “Zome” (camo) patterns.
Final Verdict
The Spyderco Delica 4 is the definition of a tool. It doesn’t rely on gimmicks, bearings, or trends. It relies on geometry, ergonomics, and reliability.
If you are a knife enthusiast, you probably already own one. If you are just looking for your first “good knife,” this is the best place to start. It sets the bar for what a folding knife should be. It is, quite possibly, the best EDC knife under $100.
