SOG marks four decades with a limited, 500-piece run honoring its original MACV-SOG combat bowie root.

To mark four decades in business, SOG Knives has released a limited-edition homage to the blade that started it all: the 40th Anniversary Fat Guard Bowie. Drawing direct design cues from the original S1 Bowie introduced in 1986, the new release pays tribute to the covert fighting knives carried by MACV-SOG personnel during the Vietnam War.

Historical Roots, Modern Production

The 40th Anniversary model centers around a 6.1-inch clip-point blade forged from AUS-8 stainless steel. SOG finished the steel with a black PVD coating for added corrosion resistance and reduced reflection.

True to the traditional combat bowie silhouette, the handle is built from stacked leather, offering a classic aesthetic alongside a contoured grip. A substantial brass guard and matching butt cap frame the handle assembly. Production is strictly capped at 500 individually serialized units, with each knife’s specific number etched directly into the pommel.

Commemorative Display Package

Rather than shipping as a standalone tool, SOG packaged the anniversary Bowie as a complete collector’s set. The knife sits inside a handcrafted pine display case outfitted with a clear glass viewing lid and an engraved anniversary plaque.

Accompanying the fixed blade inside the presentation box is a custom SOG 40th anniversary Zippo lighter and a signed certificate of authenticity. For field carry or storage, the set includes a heavy-duty black leather belt sheath, complete with a front-mounted snap pocket containing a touch-up sharpening stone.

The 40th Anniversary Fat Guard Bowie package is available directly through SOG’s website while supplies last.
