Spyderco Cobol Knife Gray Titanium, Satin M390 by Paul Alexander (C273TIP)
Cobol Gray Titanium, Satin is a modern interpretation of a compact folder, designed by Dr. Paul Alexander - an artist known for combining futuristic lines with pragmatic ergonomics. This model develops the idea of the Ball Joint Non-Locking mechanism , while offering a completely ambivalent character and minimalist form. The aesthetics based on clean, geometric lines are reflected in the design details, which are subordinated to the principle of utility and symmetry. This design is not just a tool - it is a thoughtful engineering object, whose design meets the expectations of users looking for an object of exceptional precision. The profiled Blade combines elements of the classic tanto with inspiration from the katana sword, creating a unique rising blade shape. The blade is made of Böhler M390 powder steel, known for its high sharpness retention, abrasion resistance and anti-corrosion properties. A saber grind was used, which increases the stability of the blade and facilitates control during precision cuts. The Blade's extended “tail” allows it to be opened with a razor-like gesture - quick and intuitive. Handle made of solid titanium plates is equipped with integrated spring arms, which - together with embedded balls - lock the blade in the open position without the use of a classic lock. Thanks to this, the design remains fully SLIPIT, and the user can use the knife in countries with legal restrictions for locking models. The whole is complemented by a reversible deep-pocket wire clip, providing comfortable, low-profile carry - for both right- and left-handed users. Cobol is a technical work of art for those who want maximum functionality and an out-of-the-box approach to design.
Paul Alexander, who holds a doctorate in mechanical engineering, combines scientific precision with artistic sensibility to create knives of refined form and functionality. His designs, such as the Parata model for Spyderco, feature innovative technical solutions and an ergonomic shape that works harmoniously with the user's hand. Drawing inspiration from everyday observations and experiences, Alexander transforms raw materials into tools with exceptional aesthetics and precision craftsmanship that reflect his deep understanding of both technology and fine art.
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), and is hardened between 59-61 HRC. This super steel is comparable to Carpenter's CPM 20CV or CTS-204P steels. Manufactured by Böhler Edelstahl in Kapfenberg, Austria.
Blade - with a hybrid tanto profile , inspired by Japanese aesthetics, was made of M390 powder steel - a material with excellent sharpness retention and high corrosion resistance. The saber grind used strengthens the tip and improves control during precision tasks. Opening is done with the extended “tail” of the blade, which works on the principle of a classic razor, without the need for a nail or both hands. In addition, the choil at the base of the blade allows a secure grip and promotes precision during work.
Handle - made of solid titanium, which provides exceptional rigidity with low weight and high corrosion resistance. Milled edges, delicate finger rests and an ergonomic grip line make the knife fit securely in the hand despite its compact size. Choil and subtle ribbing improve control and reduce the risk of accidental blade closure. The built-in Ball Joint Non-Locking mechanism, based on a double ball latch, offers a unique user experience - maintaining smooth operation and meeting legal requirements in countries that ban locking knives. The overall design is complemented by a tip-up wire clip on both sides for discreet portability and easy access. The open design not only emphasizes the technical nature of the model, but also facilitates maintenance. This is an EDC knife created for users who appreciate engineering, aesthetics and subtle functionality.

List of knife safety warnings based on requirements
Regulation (EU) 2023/988 on general product safety
(GPSR):
* Risk of injury: Use the knife carefully and always hold it by the handle. The blade is
very sharp and can cause serious cuts. Don't try to catch a falling
knife.
* Safe storage: the knife should be stored in a safe
place, out of reach of children and unauthorized persons. Use a blade guard if
is available.
* Use as intended: Do not use the knife for purposes for which it is not
intended, for example, for opening cans or loosening screws. This can lead to
knife damage or injury.
* Caution when cleaning: Use caution when cleaning the knife,
to avoid cuts. Do not use aggressive cleaning agents that can
damage the blade.
* Blade maintenance: Sharpen the blades regularly to keep them in good condition. Blunt
knives are more dangerous than sharp ones because they require more force, which
increases the risk of slipping.
* Transporting the knife: When transporting the knife, make sure the blade is secured,
for example, by using a vagina or sheath. This prevents accidental injuries.
* Keep your knife clean: Clean the knife regularly to remove any food debris
or other contaminants. This ensures safe and hygienic use.
* Do not modify the knife: Do not try to modify the knife or repair it yourself,
if you don't have the right skills. This can lead to damage to the knife
or injuries.
* Warning for children: knives are intended for adults only. Do not allow
children to use knives without supervision.
* Disposal: Dispose of used or damaged knives in a safe manner to
prevent accidental cuts.
This product is for adults only, who have knowledge and experience in handling sharp cutting tools. Improper use of the knife can lead to serious injury. The blade of the knife is very sharp and can quickly cut through skin and tissues; so always be very careful when slicing and do not bring your hand close to the cutting edge. To avoid slipping of the knife, it is recommended to cut on a stable and non-slip surface and avoid excessive pressure, which can cause uncontrolled movement of the blade.
Be aware that leaving a knife on the edge of a table, countertop or in easy-to-reach places, especially for children, is a danger. The knife should always be properly secured after finishing work, preferably by putting it down on a stable surface or storing it in specially designed blocks, sheaths or on magnetic strips. Never use a knife for tasks for which it is not intended, such as opening cans or using it as a lever, as this risks both damage to the tool and dangerous accidents.
Blunt blades pose an increased risk of injury because they require more force and tend to slip off the material being cut. Therefore, care should be taken to sharpen the knife regularly to maintain optimal sharpness. It is also necessary to clean and dry the tool regularly to prevent corrosion and bacterial growth. It is recommended to periodically inspect the condition of the handle and blade to detect any cracks, chipping or loosening. If damage is found, the knife should be immediately repaired or replaced with a new copy.
When using the knife, focus solely on the task at hand, avoid talking on the phone or watching TV while slicing, and make sure your work area is well-lit. You are reminded that in some countries or regions there are laws restricting the possession and carrying of knives. Before buying or using a knife, it's a good idea to make sure that using it in your location is allowed under the current law.
Adherence to the above rules will enable safe and efficient use of the knife, minimizing the risk of accidents and ensuring the long life of the tool.
