Meet the Spyderco Tenacious Lightweight Folding Knife (Model: C122PBK | UPC: 716104013890)—a go-to everyday carry folder built for people who want reliable cutting performance, comfortable grip, and lightweight carry without sacrificing Spyderco’s signature usability. Featuring a 3.39" plain-edge satin blade made from 8Cr13MoV stainless steel and a black FRN handle with bi-directional texturing, the Tenacious Lightweight is designed to be the kind of knife you actually carry and use—day after day.
If you’re shopping for a Spyderco Tenacious Lightweight, a 3.39-inch folding knife, or a plain edge EDC knife with FRN handle, this model checks the boxes for value, ergonomics, and real-world practicality.
Built for Everyday Carry: Lightweight, Tough, and Ready
The “Lightweight” version of the Tenacious is all about smart carry. The FRN (fiberglass-reinforced nylon) handle helps reduce overall weight while keeping the grip durable and use-ready. FRN is known for its strength-to-weight performance, making it ideal for EDC users who want a knife that disappears in the pocket but still feels solid in hand.
The black handle features Spyderco’s bi-directional texturing, a grip pattern designed to provide traction in multiple directions. Whether you’re working with gloves, dealing with wet conditions, or just want a handle that stays planted during demanding cuts, this texture helps deliver confident control.
3.39" Plain-Edge Satin Blade for Clean, Efficient Cutting
At the core of this knife is a 3.39-inch plain-edge blade finished in a clean satin. Plain edges are a favorite for EDC because they:
Slice smoothly through cardboard, rope, food, and plastics
Are easier to maintain and sharpen
Excel at controlled, precise cuts
The blade steel is 8Cr13MoV stainless steel, a popular choice in value-focused performance knives thanks to its practical balance of:
Corrosion resistance
Everyday edge retention
Ease of sharpening
In other words, it’s a steel that fits the Tenacious mission perfectly: a dependable user knife you can keep sharp without a complicated maintenance routine.
Spyderco Ergonomics and a Grip You Can Trust
Spyderco has a reputation for building knives that feel like tools—not toys—and the Tenacious Lightweight follows that tradition. The handle shape is designed for real hand comfort, helping reduce fatigue during repeated cutting tasks. Pair that with the bi-directional FRN texturing, and you get a folding knife that stays controllable during push cuts, pull cuts, and slicing motions.
This is especially valuable if you use your knife for:
Workday utility cutting
Shipping and receiving tasks
Warehouse, shop, and field use
Outdoor chores and general-purpose cutting
Pocket Clip Included for Secure, Consistent Carry
A great EDC knife needs to carry well, not just cut well. The Spyderco Tenacious Lightweight includes a pocket clip, giving you a stable, repeatable way to carry it. A clip helps keep the knife positioned the same way every time you reach for it—making daily use faster, easier, and more consistent.
Whether you’re clipping it to jeans, work pants, or a bag pocket, the clip adds that “ready when you are” convenience that EDC users expect.
