The Remette Cosmic Blue Titanium, Pearlescent M390 (RTCO-TB) is a premium EDC folding knife designed for users who expect high-quality materials, smooth mechanics, and modern aesthetics. The model features a blade made of Böhler M390 steel, a handle made of blue Titanium, a Compound grind, and a Pearlescent finish, which gives the blade a distinctive, elegant pearlescent effect. Opening via  flipper or thumb stud allows you to choose the opening method that suits your preferences, and the Button Liner Lock combines the convenience of a button with the mechanical stability of a liner lock. This is a refined folder for everyday carry, collecting, and working with lightweight utility materials.

Böhler M390 – premium steel for demanding EDC

Böhler M390 is a premium powder-metal steel, valued in folding knives for its excellent edge retention, high wear resistance, and enhanced corrosion resistance. In the RT-Cosmic model, it excels at precisely cutting cardboard, tape, packaging, cord, plastics, and other materials encountered in everyday use. M390 steel is well-suited for EDC designs, where edge durability and predictable blade performance are key. The lack of confirmed hardness data from the manufacturer is indicated in the table as n/a, without adding unconfirmed values.

Drop Point, Compound, and Pearlescent Finish

The Drop Point profile blade provides versatile geometry for everyday tasks, combining a strong tip with a controlled cutting line. The Compound grind emphasizes the knife’s technical character and allows for a combination of cutting performance with a distinctive blade aesthetic. The Pearlescent finish gives the surface a subtle, pearlescent effect that sets the Cosmic model apart from more classic EDC folders. This solution not only enhances the knife’s visual appeal but also complements the cool tone of the titanium handle.

Flipper, thumb stud, and smooth ball-bearing operation

The Remette Cosmic RTCO-TB offers two convenient opening methods: flipper and thumb stud. The former allows you to quickly deploy the blade with a flick of your index finger, while the latter provides greater control for a smoother, more precise opening. The pivot mechanism is based on Bearings, ensuring smooth and pleasant blade operation in everyday use. This combination suits the character of a premium EDC knife, where ergonomic handling is just as important as the quality of materials.

Button Liner Lock – the convenience of a button and the stability of a lock

The Button Liner Lock combines the comfort of a button release with the structural logic of a liner lock. Once opened, the blade is securely locked in place, and releasing it is quick and intuitive. This solution makes the knife comfortable for everyday use, especially when frequently opening and closing it while working with packaging, ropes, or other lightweight materials. The mechanism complements the smooth action of the flipper and pivot, creating a cohesive, modern folding design.

Blue Titanium – a titanium handle with technical elegance

The handle made of blue Titanium ensures high mechanical resistance, low weight relative to durability, and a distinctive, cool premium finish. The Blue / Ceramic Sandblasted surface gives the knife a matte, modern look and complements the pearlescent effect of the blade. The right-handed, tip-up titanium clip makes it easy to carry the knife in your pocket every day. The slim profile, clean lines, and refined proportions make the RT-Cosmic a perfect fit for both an EDC setup and a more collector-oriented choice.
