The Delica 4 has long been a staple of Spyderco’s EDC lineup. It’s lightweight, has a well-designed handle, and fits comfortably into any pants pocket. But the use of ZDP-189 blade steel is a relatively recent upgrade. A powdered metal made by Hitachi, this stainless steel is composed of 3 percent carbon, lending it excellent edge retention and a hardness of about 64Rc. Slightly larger than the blade, the handle features FRN scales and a lockback design, plus a four-way pocket clip for tip-up, tip-down, right-handed, and left-handed carry.
