CobraTec Large FS-3 OD Green OTF Knife
The CobraTec Large FS-3 in OD Green combines an aluminum handle, a D2 steel blade, and a dual action ambidextrous mechanism for both blade deployment and retraction.
Detailed product description
The CobraTec Large FS-3 OD Green is an OTF knife designed for everyday carry and practical use. For this series, the manufacturer specifies a high-grade aluminum alloy handle and a D2 tool steel blade. In the Large size, this model offers proportions suited to users who prefer a fuller grip and a longer blade.
