SOG - S1 5th SF Group - Vietnam - Collector's knife
VINTAGE & COLLECTOR 1986
SOG S1 5th SF Group, Vietnam
First numbered edition (of 1500 pieces) even before the brand's famous “square logo”!
This example bears the number 0770
A SOG icon, the S1 is a faithful replica of a combat knife specially ordered from Japan for an elite US unit in the Vietnam War.
Design and production by Hattori!
Often imitated, never equalled, it's still in the SOG catalog almost 40 years after its first appearance!
Today's versions are made of stainless steel and are industrially produced; quite the opposite of the first models, which were produced at HATTORI, then at Seki Japan by craftsmen, in SK5 carbon steel.
Technically :
SOG S1 models were produced at SEKI from 1986 to 2005.
This S1 series is the only one to be marked “SOG SPECIALTIES”!
Overall length 28cm
18cm blade in SK5 carbon steel with “blued” finish
Blade thickness 7mm
Stainless steel guard and pommel, matte finish
Handle in polished leather washers with synthetic inserts
Lanyard hole with original lanyard
Original leather sheath with stone

The hilt bears a few small traces of oxidation, giving it a more “field” than “showcase” feel!

Our opinion:
The SOG S1 is a benchmark for the brand, and in the modern history of the combat knife; this very first “SOG SPECIALTIES” edition is THE S1 to own, if you had to choose just one!
