The Cold Steel CS-17TAA Lynn Thompson Signature Kobun is a fixed-blade tactical knife built for serious fieldwork, self-defense training, and everyday carry. Lynn Thompson's design philosophy shines through in this compact fighter: a tanto-style blade paired with a ergonomic handle that prioritizes control and reliability over flash. If you're looking for a purpose-built knife that won't let you down in the backcountry or at the range, this one earns its reputation.
The Kobun's tanto blade is forged from AUS-8A stainless steel, a choice that balances edge retention with corrosion resistance and ease of sharpening. The plain edge cuts cleanly without the maintenance demands of serrations, making it straightforward to maintain field-ready in remote conditions. Paired with a Kray-Ex handle in OD Green, you get a grip that's tough, lightweight, and built to function in wet or gloved conditions—the material was engineered for tactical professionals and hasn't changed in decades for good reason.
This is a no-nonsense tool. The fixed blade design means zero wiggle and full power transfer when you need it. It ships with a sheath, so you're ready to carry or train immediately. Whether you're hiking rough country, practicing blade techniques, or adding a reliable fixed blade to your survival kit, the Kobun delivers the straightforward functionality that Cold Steel is known for. No frills, just steel and polymer that work.
