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, DLT Trading 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-5 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 and will fit upcoming models such as the STS-8 as well as other proposed models. Proudly made in America by Bark River Knives.
