The Curtiss Knives Warhawk 375 is a mint-condition, pre-owned American custom folder from the personal collection at We Buy Knife Collections. Built with a stonewashed M390 drop point blade, a full titanium frame lock, and a deeply milled torched titanium handle, this Warhawk has the kind of overbuilt feel that has made David Curtiss’ knives so respected in the tactical and everyday carry world.
This example has a strong visual presence without feeling decorative for decoration’s sake. The milled titanium handle gives the knife real grip and texture. Meanwhile, the torched finish adds blue, bronze, gold, and dark heat-colored tones across the frame. As a result, the knife feels rugged, mechanical, and collectible at the same time.
Curtiss Knives Warhawk 375 With Milled and Torched Titanium
The Curtiss Knives Warhawk 375 is often viewed as a more robust evolution within the Curtiss lineup. It has similarities to the Cruze, yet the Warhawk brings a beefier profile and a more hand-filling build. The frame contouring, single finger groove, and full-length milling pattern work together to create a secure grip.
That ergonomic confidence is one of the strongest parts of this knife. The handle indexes naturally, while the milled titanium adds traction without feeling overly sharp. In addition, the ridged titanium backspacer gives the hand another controlled contact point. For collectors who appreciate knives that feel as serious as they look, this Warhawk delivers.
The 4-inch M390 blade is finished with a blasted and stonewashed treatment. That finish suits the design well because it keeps the knife practical, subdued, and ready for use. M390 is widely respected in high-end folders for edge retention, stainless performance, and premium cutting capability. Here, it pairs well with the Warhawk’s heavy-duty titanium build.
S.P.O.T. Pivot, Frame Lock Strength, and Curtiss Engineering
David Curtiss is known for building hard-use folders with smart mechanical features. This Warhawk includes the S.P.O.T. pivot system, short for Stop Pin Over Travel. That system locks the pivot into place with the stop pin on the lock side. It also provides lockbar over-travel protection, which adds confidence to the frame lock design.
The knife also features a hidden high-strength hardened stop pin, caged bearings, and a replaceable D2 lock insert. Together, those features help support smooth action, long-term wear resistance, and dependable lockup. The recessed titanium pocket clip, marked with the Curtiss Knives crosshairs logo, finishes the knife with a clean tip-up carry setup.
While the Warhawk has a tactical foundation, it is not a rough or unfinished tool. Instead, this build shows the balance Curtiss does well. It feels overbuilt, yet it still has refinement. It looks aggressive, but it also carries a high level of machining detail.
From the Personal Collection at We Buy Knife Collections
This Warhawk comes from the personal collection at We Buy Knife Collections and is offered in mint pre-owned condition. That point matters for collectors who want a serious Curtiss folder without heavy signs of carry or use. The knife includes its case and Curtiss Knives patch, as shown in the product photos.
The torched titanium finish gives this example extra personality. Every ridge catches light differently, so the handle shifts between bronze, blue, gold, and darker heat-toned colors. Because of that finish, this Warhawk photographs well and stands apart from a standard stonewashed titanium build.
