TRM BullDog River-Lok - 3D Titanium

Three Rivers Manufacturing Bulldog: Compact Muscle, Built in the USA

The Bulldog from Three Rivers Manufacturing is their most robust folder to date—designed to be small enough for everyday carry but strong enough for real work. With a thick blade stock, stainless liners, TRM's River-LOK system, and a range of scale options including Micarta and Titanium, the Bulldog earns its name.

Note from Lone Star Knife & Supply
I’m Chris, and the Bulldog has that dialed-in TRM feel—clean lines, great ergos, and smooth action. The River-LOK is crisp, the blade feels sturdy, and the overall package is just fun to carry and use. It’s compact, but never feels small in the hand.
