Named for its optimal use of space, the Spyderco Efficient offers a full-length grip without taking up too much room in the pocket. The Efficient is only four inches long when closed, but usable space increases when open thanks to an integrated finger choil in the blade, ensuring there is plenty of space for a full hand hold.

"Efficient" can also refer to this blade. The 8Cr13MoV drop point is versatile for everyday carry and easy to sharpen with respectable edge retention. The angle of the handle enables the point to be used with great precision, much like a good Wharncliffe blade but retains enough belly for efficient cutting. A full flat grind further increases the slicing abilities of the blade.

Spyderco's signature round opening hole easily swings the blade open from the textured G10 handle scales. Skeletonized liners and a solid metal backspacer impart plenty of strength to the structure of the knife and ensure the liner lock is nice and strong. A large lanyard hole and reversible, tip-up pocket clip add enough versatility to ensure both right and left-handers can easily carry the Efficient.
