The SOG S1 Bowie Vietnam 5th Special Forces Group is one of the most representative knives in the history of SOG Specialty Knives and the model with which the American brand began its production during the second half of the 1980s. Made in Seki, Japan, the S1 was created as a tribute to the famous knives used by members of the Military Assistance Command, Vietnam – Studies and Observations Group (MACV-SOG) during the Vietnam War.

It is important to distinguish the S1 from the original “sterile” military knives actually used operationally during the conflict: the commercial SOG model instead reproduces the commemorative configuration of the famous MACV-SOG Bowie, featuring the U.S. Army Special Forces crest on the blade together with the marking “VIETNAM 5th SPECIAL FORCES GROUP”. This strong historical identity, combined with the quality of Japanese manufacturing, has made it one of the most recognizable and sought-after vintage SOG knives among collectors.

Production was entrusted to Ichiro Hattori in Seki, one of the most important names in Japanese knifemaking. The substantial Bowie blade is made from SK-5 carbon steel, hardened to approximately 57-58 HRC, with the characteristic dark gun-blue finish combined with polished surfaces. The handle uses traditional stacked leather washers stabilized with epoxy resin, completed by a sturdy metal guard and pommel.

This example features the classic SOG Specialty Knives logo on one side of the ricasso and, on the opposite side, the markings “SEKI-JAPAN”, the Special Forces crest and the inscription “VIETNAM 5th SPECIAL FORCES GROUP”. It is also accompanied by its original black leather sheath, complete with sharpening stone pocket and a large Special Forces crest embossed on the lower section. The original period identification label is still present on the back of the sheath.

The example offered here comes from a private collection and has actually been used. The blade shows scratches, abrasions and surface marks, both on the blued and polished areas; the leather handle has developed a noticeable patina and shows wear consistent with its age. The original sheath is also heavily used, with leather wear, marks and widespread abrasions. Its condition should therefore be considered good in relation to its age and nature, but it should not be compared with a display-grade or NOS example.

These very characteristics tell the story of an authentic SOG S1 made in Seki: a knife that, regardless of its cosmetic condition, retains all the appeal of one of the founding models of the brand and today represents a particularly significant piece for a collection dedicated to American military knives and Japanese SOG production from the 1980s and 1990s.

Created in 1986 as the second official model of the newly formed SOG Specialty Knives, the S2 Trident is not just a knife, but a bridge between the past and the present. Designed in honor of the Navy SEALs and special units that operated in Vietnam, it draws direct inspiration from the legendary MACV-SOG knives of the 1960s, “sterilized” and lethal tools used in the most secret missions of the conflict.

Produced during the company's golden age in Seki, Japan, the Trident combines elegant lines and combat functionality: a thick, balanced AUS-8 steel Bowie blade with impeccable satin finish; ergonomic and durable black micarta stacked washer handle; and the engraved Navy SEAL symbol, a seal of belonging to an elite group. The leather sheath with sharpening stone completes a package designed for operators and collectors.

The S2 Trident is the most refined tribute to SOG's operational past: a homage to the military tradition of Vietnam reinterpreted with Japanese craftsmanship. Today, with a very high rarity index, it is considered one of the most sought-after pieces by military knife collectors, not only for its build quality, but for the history embodied in its blade.

Japanese steel meets Italian excellence

For this 2021 collaboration between Coltelleria Collini of Busto Arsizio and Fox Knives of Maniago, we decided to offer the 609OD Bushman, an outstanding bushcraft knife produced by Fox Knives of Maniago, using high-performance Japanese V-Toku2 Sanmai steel (5mm) from Takefu Steel instead of the D2 steel used in the standard model.

Specifically, we used high-carbon V-Toku2 at 62/63HRC for the central core and stainless SUS410 for the outer layers, ensuring exceptional cutting ability, penetration, and edge retention. At the same time, the blade offers high corrosion resistance and increased toughness due to the laminated structure and external stainless steel.

Technical Specifications

Like the ancient swords of the Japanese Samurai.

The laminated steel—imported into Italy by Collini Steel directly from Takefu Steel in Japan—follows the ancient Japanese tradition of crafting legendary Samurai swords. As early as the 1100s, Japanese blacksmiths combined different materials to create Katana swords with incredible cutting power, strength, and flexibility, unmatched at the time. This revolutionary forging technique has allowed Samurai swords to survive to this day as some of the most fascinating objects ever created.

By applying this tradition to modern metallurgy, we now have technologically advanced steels that have been tested and widely used in knife-making by renowned brands such as Fallkniven, Cold Steel, Mcusta, Kai, Sog, Zwilling, Rockstead, and more.

San Mai Steel Features: This consists of different types of metals fused together to create a composite steel that enhances and intensifies the individual strengths of each material:

• Longer-lasting cutting edge: High-performance, high-carbon core steels (VG10, CoS, Shiro) or sintered steels (SPG2) provide exceptional hardness and cutting performance after heat treatment.
• Increased toughness: Inspired by Japanese sword-making, the multi-layered steel is highly resistant to breakage due to the toughness of the core steel and the flexibility of the outer stainless steel layers.
• Improved corrosion resistance: The outer stainless steel layers provide high corrosion resistance. The galvanic combination of Takefu Steel’s materials further enhances resistance along the edge.
• Ease of reworking after heat treatment: Unlike standard steels, the outer layers retain some softness even after hardening, allowing for easier processing, drilling, and welding.
• Enhanced aesthetics: Multi-layered or Damascus-patterned knives are visually striking, elegant, and highly sought after by collectors worldwide.
