Named after its principal job function, to assist, the Spyderco Assist Black Blade is a lightweight folder for emergency fire/rescue professionals who rely on knives to be straightforward in use and perform flawlessly.
The blade is covered in non-reflective black carbon nitride with a patented lift-and-pry (blunt-nose) shape constructed from high-carbon VG-10 stainless steel and loaded with teeth. Most of its 3-3/8" (86mm) cutting edge is serrated, with the last inch at the tip left PlainEdged. Above the one-hand-open hole sits a feature called a Cobra Hood™.
A metal cap that directs the thumb over the hole for quick, by-feel opening and doubles as a textured leveraging platform for your thumb during cutting. A wavy design cut out of the top of the blade and again along the handle is for controlled cutting. You can squeeze the blade shut by placing a rope in the groove (between the partially open blade and handle) and slicing and trimming the rope in a collected movement without fully exposing the cutting edge.
The lightweight black handle is constructed from fibreglass-reinforced nylon (FRN) with a survival whistle built into the butt end, sharp and high-pitched enough to detect you. A toughened wire pocket clip attaches through the handle on either side for left- or right-hand use.
A retractable and replaceable carbide-tip glass/ice breaker is housed inside the handle and is exposed when the closed blade is compressed into the handle, retracting when pressure is released.
