Spyderco Endura 4 Folding Plain Edge

Although the Spyderco Endura was first manufactured in 1990 along with the Delica model, Spyderco hasn’t stopped improving the Endura or Delica line of knives. Spyderco Endura 4has refined quality, VG-10 steel with a reinforced nylon handle that is made for performance.

The Endura 4 is long for a folding knife at 8.75″ when fully opened. When folded, it’s 5″ handle hides the three-inch blade. The handle’s construction makes the knife comfortable to handle and slip-resistant to carry out a variety of tasks. This is perfect for taking the Endura fishing when hands might be wet from handling fish, fishing lines or hooks. The steel is also rust-resistant.

There’s nothing that the Endura 4 can’t accomplish. It performs as well as any non-folding knife out there on the market. The Spyderco brand of EDC knives all have a unique look that is truly a trademark of the company, and the Endura 4 is no exception.

The large blade of the Spyderco Endura 4 is made of VG-10 high-quality steel. The steel is strong and takes a razor-sharp edge notorious in that type of steel. The spine has jimping for a firm grip. This is considered by most customers as a great self-defense knife as well as a versatile utility knife.

The blade is easy to open with its large 13 mm hole for gripping. Once open, it locks into place and has no wiggle room at all. Many knives have a bit of play in the locking mechanism, which makes it difficult to perform tasks that require strength and precision, but the Spyderco Endura 4 doesn’t have that problem.

The VG-10 steel blade has a flat edge from the end of the choil to the very tip, which makes it easy to slice, chop or poke holes into an item. The strength of the steel keeps the blade sharp over many uses before it needs to be sharpened.

The Spyderco Endura 4 FRN handle offers a bi-directional grip. The fiberglass reinforced nylon has lightweight steel frames inside to provide added strength to the construction and for attaching the screws and hardware. The screws and hardware are attached in a way that allows for easy cleaning and reassembly. They also make the opening and closing of the folding knife extremely smooth. It locks into place smoothly and firmly. There’s no wiggle or play in blade when it’s stowed into the handle.

The handle itself is textured to keep the knife from slipping during strenuous activity and use. There’s also jimping and finger grooves in the handle to guide finger placement and remove slippage problems. Many people consider the FRN handles with texture more aesthetically pleasing too.

The clip has been upgraded from its original two-way clip available in previous incarnations of the Endura to a four-way clip that allows freedom of movement. Anyone can use the Endura because it’s now more ambidextrous. The clip allows not only left- and right-handed users, but can be clipped tip-up or tip-down depending on personal preference.
