Spyderco Delica 4 Review

Spyderco Delica 4 Flat Ground FRN reviewThis is yet another masterpiece from Spyderco. If you are a proud owner of a Delica, then you should know just how much quality and dependability is packed into its small package. The Delica 4 is definitely no exception with added choices when it comes to the color of the handle. You can get the Delica 4 Flat Ground folder with the fiberglass reinforced nylon (FRN) that comes in various colors. Personally, I like the blue handle because it makes it look cool. But with all kidding aside, the Spyderco Delica 4 is a serious knife that can even handle tasks that are a bit beyond its normal weight class.

The Spyderco Delica 4 weighs a measly 2.3 ounce which makes it perfect for everyday carry and even self-defense. If you happen to bring it on a camping or hunting trip during the weekend, the brightly colored FRN handle makes it virtually impossible to lose because it has a strong contrast against the natural earth colors. The Spyderco Delica 4 comes with a VG-10 blade with a relatively high level of carbon as well as a other elements such as Manganese, Molybdenum, and Vanadium which gives it a strong resistance to normal wear. This strong wear resistance can make the Delica 4 a bit stubborn when it comes to sharpening but that can be remedied by a bit more pressure. The leaf blade has the signature Spydie Hole that is a bit larger than other folders in its weight class but does becomes very useful in opening the knife. The blade comes from Japan but the knife itself is assembled in Golden Colorado, USA.


The handle has the FRN scales with what is known as bi-directional texturing that improves the grip and thus making it a lot safer to handle. The handle also has the normal finger groves for a more comfortable grip especially since the top of each grove has been smoothened out. The handle also has a stainless steel lining that improves strength and durability but the downside is it adds considerable weight even though they have been “skeletonized”. The steel liners also improve the strength of the pivot which is crucial for folders of Delica 4’s size. They prevent blade play which is yet another attribute common to Spyderco folders.

The Delica 4 uses what is known as a lock back. The blade has a relatively deep cutout which is where the lock back locks into. This causes the lock to be very strong and stable considering its relatively thin profile. This dent is referred to as a “David Boye Dent” by Spyderco. With this mechanism, you can rest assured that the lock will not disengage even when handling the knife with considerable force. It is also designed in such a way that it does not dig into your hand or cause any discomfort showing just how well designed the Delica 4 really is. The overall construction of the knife is nothing short of excellent, just what you would expect from a Spyderco knife. This is also why the Delica line of knives is quickly becoming one of the flagship knives of the company.
