Blade Material

The blade is what makes a knife. This makes it an essential part of the knife. The Delica 4 from Spyderco features decent VG-10 steel in its construction. VG-10 is a Japanese steel that was designed for chefs. When blade makers noticed how useful the steel was, they started manufacturing pocket blades with it. Iron, chromium, carbon, vanadium, molybdenum, manganese, and cobalt combine to form VG-10 steel. This type of steel is known to possess exuberant properties that make it ideal for everyday use. It is extremely corrosion-resistant and quite sharp to facilitate speedy applications.

Blade Design

Delica 4 features a flat-grind drop point blade design. This style makes the knife ideal for handling various tasks in the outdoors. These tasks include skinning, carving, and cutting through cardboard and thick plastics. Also, you can use it to cut and dice fruits and vegetables. The blade exhibits versatile functionality because it is thicker towards the tip. You are less likely to puncture things you don’t intend to, thanks to its drop point design. In addition to that, the design ensures a well-balanced grip to hold the knife in different ways as it offers numerous index points. Straight out of the box, the knife comes extremely sharp. The drop point style allows it to stay that way for long after several applications. The thumb hole is ergonomically well placed on the blade, allowing the blade to be opened easily with one hand.


Weight, Size, and Portability

All pocket knives are built for the outdoors. And since they are meant to increase portability, the weight and size matter a great deal. The Spyderco Delica 4 comes with all the bells and whistles for outdoor use. Weighing as little as 2.5 ounces, the knife makes an excellent EDC option. When in the pocket, you can barely feel its weight.

The quad-mount pocket clip ensures you carry this knife in different positions, i.e. the tip facing up or down and left or right-handed carrying. This feature provides individual preference. The blade has a nice-sized hole for carrying the knife with a paracord or lanyard.
When open, the knife measures 7.15” as the overall length and 2.8” blade length. However, do not let the size fool you. When in action, it handles the applications quite efficiently.


The handle on this Delica 4 features fiberglass-reinforced nylon material in its construction. Also, stainless steel is skeletonized in the liners for better gripping. The scales on the FRN possess a bidirectional texture to enhance a solid grip. What’s more, the small notches included on the back and bottom part of the handle enables heavy usage and prevents fingers from sliding when in use. The blade is perfectly placed in the handle, leaving no inconsistent gaps between the liners.

Locking Mechanism
