SATRE S600 BLACK

In Neck Knife mode, using a 550 paracord lanyard, it can be worn around the neck while keeping the knife vertical with the handle facing downwards.

The metal eyelets on the pre-shaped Kydex sheath allow for the attachment of both the lanyard and the accessory holder.

Starting from January 2022, available exclusively on (https://www.extremaratio.mom) as an optional accessory, the ULTICLIP system allows the sheath to be attached not only to belts, but also to pockets, pants, jackets, shirts, and t-shirts.

ULTICLIP enables both horizontal and vertical positioning of the knife, making it suitable for both left- and right-handed users. All three versions of the Satre are delivered with a black sheath. The desert sheath will be available separately as an optional accessory.

The skeletonized full-tang structure allows you to customize the knife by using Paracord as a handle wrap.

Satre is available in three versions featuring two different types of steel:

The Black and Stone Washed versions use Böhler N690 heat-treated to 58 HRC. This material is chosen for its oxidation resistance, edge retention, and above all, the reliability it has proven over the years.

The Black S600 version uses Böhler S600 steel instead. This steel is used in industrial manufacturing to make metalworking tools and production molds.

Its high content of molybdenum, tungsten, and a balanced presence of vanadium in its chemical composition grant it excellent hardness, wear resistance, and toughness.

The presence of Cobalt fosters the formation of small, uniformly distributed carbides—a feature that enhances and elevates wear resistance.

The Satre S600 is hardened and cryogenically treated, achieving an exceptional hardness of 64 HRC.

This provides high wear resistance and long-lasting edge retention capabilities.

Böhler S600 contains 4.5% chromium, making it a carbon/oxidizable steel.

For this reason, Extrema Ratio has chosen the new EXP DARK coating.

Its high hardness, wear resistance, and abrasion resistance make this steel challenging to sharpen.

To ensure that your SATRE always retains a razor-sharp edge, we recommend using the dual-grit (diamond-ceramic) sharpener produced by Extrema Ratio.

SATRE NITROGEN

The icon evolves, the mission remains the same. Designed in collaboration with Daniele Dal Canto, AIGS guide, the SATRE delivers maximum performance to those who need a compact tool. Outdoor, bushcraft, urban EDC. Today the range expands with the introduction of new high-visibility colorways in Nitrogen steel.

COMPACT. RELENTLESS.

SATRE is a compact fixed-blade knife. The skeletonized full-tang structure allows you to customize the grip using Paracord. Housed in its black pre-shaped Kydex sheath, it is designed to operate as a Neck Knife, backup knife, or as a primary element in a multifunction kit.

The metal eyelets on the sheath enable ambidextrous, vertical, or horizontal attachment to any type of clothing. The family expands with the new Nitrogen steel versions (Orange and Yellow): they guarantee ease of resharpening, extremely high corrosion resistance, and immediate visual spotability on field terrain.

These new additions join the four classic models of the series: the N690 versions (Black, Expeditions, and Stone Washed), which represent Extrema Ratio's historic balance, and the S600 steel variant (64 HRC), dedicated to those seeking exceptional hardness performance.
