The blade, sharpened only on one side, ensures lethal accuracy, while the absence of guards prevents any risk of entanglement in close, high-intensity combat.

ExtremaRatio - Col Moschin Compact in San Mai V-TOKU2 - Limited Edition - PRIVATE COLLECTION - Knife

For this 2020 collaboration, exclusively for Coltelleria Collini, we decided to offer a series of best sellers produced by Extrema Ratio. These knives are made using the renowned San Mai steel produced by Japan’s Takefu Steel. Specifically, we used carbon-rich V-Toku2 at 62/63HRC for the central core and stainless SUS410 for the outer layers, resulting in superior cutting performance, penetration, edge retention, ease of sharpening, and at the same time excellent corrosion resistance and increased resilience due to the laminated structure.
Model Col Moschin Compact: this First Production Run was limited to 15 numbered units, from 1 to 15.
The lethal efficiency of the COL MOSCHIN knife, now in compact version. Comes with a rigid belt sheath and BELT-CLIP. The sheath can be mounted horizontally, vertically, or at a 45° angle.
Usage: tactical, sports, hiking, collecting
Blade: full tang, laminated Japanese steel (San Mai) with cutting edge in V-Toku2 (carbon steel) at 62/63HRC and outer cheeks in SUS410 (stainless)
Handle: Forprene
Blade length: 110mm
Blade thickness: 6.5mm
Overall length: 212mm
Balance: 0.5cm behind the guard
Weight: 209g
Sheath: ABS with multi-position Tek-Lok attachment
Notes: Numbered edition - cardboard box with Extrema Ratio logos and certificate - as the cutting edge is carbon steel, it is recommended to lightly oil the blade to maintain its condition.As in ancient Japanese Samurai swords.
The laminated steel – imported into Italy by Collini Steel directly from Japan’s Takefu Steel – is based on the age-old Japanese sword-making tradition. As early as the 1100s, Japanese blacksmiths were combining different metals to craft Katana swords with extraordinary cutting power, resistance, and flexibility. This revolutionary technique allowed Samurai swords to survive through centuries and become among the most fascinating human-made artifacts. Applied to modern metallurgy, this tradition now yields advanced steels already used in knife-making by brands like Fallkniven, Cold Steel, Mcusta, Kai, Sog, Zwilling, Rockstead, etc.
San Mai Steel Features: A combination of different metals bonded together to create a composite with amplified properties:
- Greater edge retention
Thanks to high-carbon premium steels (VG10, CoS, Shiro) or powder steels (SPG2) in the core, once hardened, the blade achieves cutting performance far superior to traditional steels.
- Higher resilience
Based on Japanese sword construction, the multi-layer steel is highly resistant to breaking due to the toughness of the core and flexibility of the stainless cladding.
- Improved corrosion resistance
The outer stainless layers ensure high corrosion resistance. Takefu’s multi-metal bonding also enhances galvanic protection of the edge.
- Easy processing post heat-treatment
Despite being hardened, the outer layers retain softness, allowing easy drilling, grinding, or welding. Cryogenic treatment is recommended for optimal performance.
- Enhanced aesthetics
Multi-layer or Damascus-patterned knives are elegant, refined, and highly valued by collectors worldwide.For more information: collinisteel

The Sethlans is available in two versions with two different types of steel.
The Black version uses D2 steel, heat and cryogenically treated to 60 HRC, which has a high regrindability even with makeshift tools. To give greater hardness and resistance, the blade is coated with the new Teflon-based product “EXP DARK” offered by Extrema Ratio.
The knife comes with G10 scales featuring the ergonomic design characteristic of Extrema Ratio handles. They can be removed to reveal the skeletonized structure of the knife, which allows for maximum lightness with minimum thickness. For lovers of extreme customization, the full-tang structure allows the handle to be coated with paracord.
The sheath is made of a lightweight, minimalist Kydex. It can be disassembled and adapted for both left- and right-handed users. The addition of an optional belt clip allows the knife to be positioned either vertically or horizontally and makes the sheath much more versatile than the textile version. It also comes with a mini pouch with a M.O.L.L.E. system containing a double-sided sharpening stone and a firesteel for lighting fires.

* Checked and Certified by our in-house laboratoryThis Ka-Bar 1217, made in 1991, is a commemorative knife designed to mark the 50th anniversary of the Japanese attack on Pearl Harbor on December 7, 1941. This surprise attack, conducted by the Imperial Japanese Navy, aimed to destroy the U.S. Pacific Fleet and prevent a rapid response to Japanese expansion. The raid claimed the lives of about 2,400 people, including military personnel and civilians, and led the United States to enter World War II, declaring war on Japan the following day.
The Ka-Bar 1217, with its high-carbon steel blade and leather ring handle, has the same design as the legendary Ka-Bar knife used by U.S. soldiers during the conflict. The blade is engraved with the 50th anniversary logo and a symbolic image of Pearl Harbor, making the knife a collector's item and a tribute to the historical memory of the event. The Ka-Bar 1217 is not just a tool but a mark of honor and respect for the victims of the attack and the heroes who contributed to the victory of the United States during World War II.
Unlike the standard models, here we have engraving from the right side of the blade, hand-molded leather washers with an aged look, and even the scabbard is made like the 1940s models, with darker leather and steel staple points in addition to the traditional contrasting cream-colored stitching.

In what would become the first conflict in history to be broadcast live on television, 90,000 tons of bombs would be dropped, marking a new point of no return for what was considered acceptable by global public opinion. The imagery that war helped create would lay the groundwork for the long series of Western military interventions in the Middle East in the years that followed.
