- Slym Titanium/Dark Matter Polar Fat Carbon, Satin - an elegant folding knife from Spyderco, designed by Michele Moletta Pensato, with an M390 steel Blade and a Titanium and Polar Fat Carbon Handle. Precision, lightness and style in a premium EDC format.

This product is intended for use only by adults with knowledge and experience in handling sharp cutting tools. Improper use of the knife can result in serious injuries. The blade is extremely sharp and can easily cut through skin and tissue; therefore, extra caution should always be exercised while cutting, and hands should be kept away from the cutting edge. To prevent the knife from slipping, it is recommended to cut on a stable, non-slip surface and avoid excessive force, which may cause uncontrolled blade movement.
Leaving the knife on the edge of a table, countertop, or in easily accessible places—especially where children are present—poses a significant safety risk. The knife should always be properly secured after use, ideally by placing it on a stable surface or storing it in designated knife blocks, protective sheaths, or magnetic strips. The knife should never be used for tasks it is not designed for, such as opening cans or prying objects, as this can damage the tool and lead to dangerous accidents.
A dull blade increases the risk of injury, as it requires more force and is more likely to slip from the material being cut. Therefore, it is essential to sharpen the knife regularly to maintain optimal sharpness. Additionally, proper cleaning and drying of the knife are necessary to prevent corrosion and bacterial growth. Periodic inspection of the handle and blade is recommended to check for cracks, chips, or looseness. If any damage is detected, the knife should be repaired or replaced immediately.
When using the knife, focus solely on the task at hand—avoid talking on the phone, watching television, or other distractions while cutting. Ensure proper lighting in the workspace for better visibility and control. Please note that some countries or regions have laws restricting the ownership and carrying of knives. Before purchasing or using this knife, verify that its use is legal in your location according to applicable regulations.
Following these safety guidelines will help ensure safe and effective knife use, minimizing the risk of accidents and extending the lifespan of the tool.
Slym Titanium/Dark Matter Polar Fat Carbon, Satin is a slim EDC folder, created in collaboration between the Spyderco brand and Italian designer Michele “Molletta” Pensato. This elegant design is distinguished by its modern form, lightness and careful balance, providing a sophisticated tool for everyday use. A special feature of this model is the attention to design details, which combine aesthetics with functionality, responding to the needs of advanced users and collectors. Blade is made of Böhler M390 steel , known for its excellent resistance to abrasion, corrosion and excellent sharpness retention. Blade's shape allows for precise cutting, while maintaining an elegant and technical character. The Handle is a combination of milled titanium block and Dark Matter Polar Fat Carbon composite inlay . This combination reduces weight and gives the whole thing a unique look. The frame lock mechanism provides a solid lock, and the lightweight clip allows for discreet tip-up carry. The C271TIP is a highly refined premium knife for discerning users who value modern design and functionality.
Michele “Molletta” Pensato, an Italian knife designer with a passion for archaeology, has transformed his love of adventure into the high-end craft of knife design. His career began with an archaeological dig, where he realized the need for a durable knife. Known for his innovative approach to materials and experiments with heat treatment, Pensato has won numerous awards. His designs for lionSTEEL, such as the popular T5 and the award-winning SR11, are distinguished by their practicality and typically Italian rounded shapes. Knife design, although just a hobby for him, has resulted in significant contributions to the lionSTEEL collection.
M390 - a martensitic high-performance chrome steel produced by powder metallurgy. Due to its alloy concept, it has extremely high wear resistance and high corrosion resistance. Due to its high wear resistance, it adequately maintains the shape of the edge, so the blade stays sharp for a very long time (requiring minimal maintenance). Another of the advantages is resistance to the formation of “wire” during sharpening. The steel has a high chromium content of 20.0% (Cr) doped with 1.9% carbon (C), vanadium 4.0% (V), hardened between 59-61 HRC, vacuum and cryogenic treatment and double tempering. This super steel is comparable to Carpenter's CPM 20CV or CTS-204P steels. Manufactured by Böhler Edelstahl in Kapfenberg, Austria.
Blade - with a straight back profile is made of Böhler M390 powder steel , which offers exceptional cutting properties, corrosion resistance and long-lasting sharpness retention. The surface finished with an elegant satin finish enhances the aesthetics of the blade and reduces the visibility of traces of use. The round SpyderHole cutout (Spyderco patent) makes it easy to open with one hand, and the Reeve Integral-Lock used, with a steel inlay to prevent wiping of the lock face, secures the blade when unfolded for secure operation. Blade's geometry is conducive to precise cuts and is perfect for EDC applications.
Reeve Integral Lock - (R.I.L.) reinforced, monolithic Frame-Lock type blade lock . One of the grips acts as the locking mechanism.
Handle - constructed of two contrasting materials: titanium and Dark Matter Polar Fat Carbon composite. The monolithic frame is milled titanium, valued for its structural rigidity and wear resistance, making it an excellent base for the frame-lock mechanism. The inlay is made of premium Fat Carbon Dark Matter Polar composite, a laminate that not only enhances aesthetics, but also increases grip with a subtly textured surface. The overall design has been refined for ergonomics - the contours of the Handle are smooth, and the layout of screws and holes has been reduced to a minimum, giving the design a clean, elegant look. The knife also features a two-position (right/left) low-profile deep-carry clip for discreet deep carry in tip-up configuration.
