The Bark River STS-5 came at the bequest of Force Recon special forces serving in the Middle East. To honor the people who keep us safe, we commissioned an exclusive run of these knives in a civilian version. Incredibly well built and able to handle any task that comes its way the Bark River STS is an essential for any Bark River or tactical knife fan. The STS-5 Measures 10.875″ with a 5.5″ 154CM steel blade that is .270 thick. Yes that’s right – .270 thick it’s not a misprint! The handle sets are removable and interchangeable with other STS knives ( 6 & 8). Bark River Builds a very well made and stout knife. We have sold many of them with no one unhappy customer. This knife features a green trimmed blade with Green/Black Linen Scales. The cloudiness on the blade is a protective coating added to protect the finish.
