Detailed product description
Spyderco Stretch 2 Lightweight represents the modern continuation of Spyderco’s long development line of hunting and working folding knives. Its construction is based on the need to create a lightweight, ergonomic, and exceptionally capable cutting tool that can offer a high level of working comfort even during prolonged use.
The C90FP2K390 version is especially interesting thanks to its Straight Spine design. Unlike some traditional profiles in the Stretch series, it uses a straighter blade spine, which gives it a more purposeful working character and a geometry that is easy to control.
The blade features a versatile Drop Point profile. Its shape makes it suitable for combining general cutting tasks with more precise work where tip control matters. The gradual taper toward the tip creates a practical compromise between cutting efficiency and strength in the working part of the blade.
A key construction element is the Full-Flat Grind, a full-flat grind running from the spine of the blade down to the edge. This design supports smooth passage through material and contributes to very strong cutting performance. The knife is therefore well suited for working with cardboard, rope, wood, packaging materials, and other common materials.
The plain PlainEdge edge enables precise cutting control and offers more universal use in a variety of everyday tasks. Another advantage is easier maintenance and the ability to resharpen the edge using common sharpening tools.
The ergonomically shaped handle deserves special attention. Its design is based on Spyderco’s many years of experience in developing working knives. A notable feature is the specially shaped index-finger choil, which allows the hand to be placed closer to the blade. This grip style, known as the Choked-Up Grip, provides more precise control during finer cutting tasks.
The handle features Spyderco’s characteristic Bi-Directional Texture. This two-way texturing creates greater friction and helps maintain a secure grip even when working in wet conditions or while wearing gloves.
Opening is handled by Spyderco’s signature Round Hole. It allows comfortable one-handed operation and provides enough space for thumb access.
Character and philosophy
The Stretch 2 Lightweight Straight Spine K390 is a knife designed with real working usability in mind. Its construction is not based on decorative features, but on functional geometry, ergonomics, and maximum use of available space.
Special attention was paid to comfort during long-term use. The ergonomic handle shape helps distribute pressure in the palm and allows several different grip styles. The index-finger choil also makes it possible to move to a more precise grip, giving the user better control over blade guidance.
The straighter spine of the Straight Spine variant gives the knife a more traditional feel and contributes to the characteristic look of this version. Combined with the versatile Drop Point profile, it creates a practical setup suitable for a wide range of cutting tasks.
This model is intended for users who expect above all excellent cutting performance, comfortable handling, and reliability in regular use from a pocket knife.

Possible limitations
The Stretch 2 Lightweight is primarily a high-performance cutting tool. It is not intended for prying, chopping, striking, or any other tasks that place excessive stress on the blade and locking mechanism.
The ergonomic handle is designed for comfortable handling, but its shape may not suit every user. A personal test is the best way to judge comfort.
The Back Lock requires the locking release on the spine of the handle to be pressed when closing. Users accustomed to side locks may need some adjustment at first.
The blue handle finish is more noticeable and may not suit customers who prefer a discreet look for a working or tactical knife.
Maintenance and care
Clean and thoroughly dry the knife after each use. Pay special attention to the area around the pivot, the lock, and the inner parts of the handle, where dirt and cutting residue may collect.
Check the moving parts regularly and lightly lubricate them with a suitable knife oil if needed. Use only a small amount of lubricant so that dust and dirt do not accumulate unnecessarily.
Clean the handle with a soft brush and a suitable cleaning agent. Pay particular attention to the textured surface, where small debris can collect.
Inspect the edge regularly and, when needed, gently restore it while maintaining the correct sharpening angle.
For regular maintenance, we recommend the Spyderco Tri-Angle Sharpmaker Complete Sharpening System 204MF, which is also ideal for plain edges and allows controlled, precise sharpening.
Store the knife in a dry place. Also regularly check the proper function of the lock, the condition of the blade, and the attachment of the pocket clip.
