Product Description
The Stretch 2 XL Lightweight C258FPK390 puts a blade just shy of four inches into a linerless FRN handle that weighs under three ounces. This version pairs a full-flat-ground blade in Böhler-Uddeholm K390 MICROCLEAN with blue FRN, the signature color of Spyderco's K390 family.
K390 MICROCLEAN is a powder metallurgy tool steel from Böhler-Uddeholm, developed for industrial cutting, blanking, and punching operations that demand very high wear resistance and strength. In a knife, that means long edge life through cardboard, cord, and hard daily use. The thin 0.118" blade is full-flat ground with a satin finish for clean, efficient slicing. The trade-off is care: it isn't stainless, so it needs to be kept clean and dry.
- Blade: 3.99" K390 MICROCLEAN blade with a 3.46" PlainEdge, full-flat grind, satin finish, 0.118" thick.
- Handle: Linerless blue FRN with Spyderco's Bi-Directional Texture; 4.97" closed, 0.43" thick, 2.6 oz.
- Deployment + Lock: Spyderco Trademark Round Hole for one-handed opening with either hand; a stout Back Lock holds the blade open and releases by pressing the lock bar on the spine.
- Carry: Four-position pocket clip for tip-up or tip-down carry on the right or left side; 8.90" overall.
Ideal for: EDC carriers who want a large blade in a very light knife; outdoorsmen and hunters who want long reach without the weight; and steel enthusiasts collecting Spyderco's K390 family.
Care note: K390 MICROCLEAN is a tool steel, not a stainless steel. It may patina or rust, so wipe it clean and dry after use and keep a light coat of oil on the blade.
The Spyderco Stretch 2 XL Lightweight in K390 MICROCLEAN with blue FRN (C258FPK390) ships same or next business day from Columbia, Louisiana. Knifeworks is an authorized Spyderco dealer.
Spyderco Stretch 2 XL Lightweight K390: Frequently Asked Questions
Answers to the most common questions about the Spyderco Stretch 2 XL Lightweight (C258FPK390).
What lock does the Spyderco Stretch 2 XL Lightweight C258FPK390 use?+
The Stretch 2 XL Lightweight uses a Back Lock. When the blade opens, a spring-loaded lock bar in the spine of the handle drops into a notch in the blade tang and holds it securely. To close, press the exposed section of the lock bar on the back of the handle and fold the blade, keeping your fingers clear of the edge. The lock works the same for left- and right-handed users.
What is K390 MICROCLEAN steel?+
K390 MICROCLEAN is a powder metallurgy tool steel from Böhler-Uddeholm, developed for industrial cutting, blanking, and punching operations that demand very high wear resistance and strength. It is known for long edge life. Spyderco marks its K390 knives with a blue handle color.
How do I care for a K390 blade?+
K390 MICROCLEAN is not a stainless steel, so it may develop a patina or rust if left wet or dirty. Wipe the blade clean and dry after use, especially after cutting food or handling it with sweaty hands, and keep a light coat of oil on it. Because it is so wear resistant, diamond or CBN abrasives work best for sharpening.
What is the Stretch 2 XL Lightweight blade good for?+
The C258FPK390 has a 3.99-inch blade with a 3.46-inch PlainEdge and a thin 0.118-inch full-flat grind, which makes it a strong slicer for breaking down boxes, cutting rope, food prep, and outdoor chores. At 2.6 ounces, it gives you nearly four inches of blade in a knife that carries like a much smaller one.
What comes with the Stretch 2 XL Lightweight C258FPK390?+
The C258FPK390 ships as a knife with its four-position pocket clip installed. It is knife only, with no sheath included. Packaging and included items are set by Spyderco and are subject to change.
