A pocketknife can open a box without becoming the most interesting thing in your pocket. The North Mountain Blade BBNM takes a different approach: a broad tanto blade, textured titanium, and Duane Dwyer’s unmistakably angular design language. The appeal goes beyond the next package that needs opening.

The North Mountain Blade BBNM 2522-DT, designed by Duane Dwyer, combines a titanium-alloy handle, tanto-style blade, frame lock, and pocket clip. Its angular profile draws from Dwyer’s established design approach, creating a production folding knife intended for everyday utility and outdoor activities.
With its 8.27-inch overall length and manufacturer-listed 144-gram weight, the BBNM is a full-size rather than ultralight carry option. If you like a substantial folder with a pronounced profile, that is part of the attraction. If your ideal pocketknife disappears into a pair of shorts, a smaller design makes more sense.
Duane Dwyer’s Influence on the Design
Duane Dwyer is associated with Strider Knives, a manufacturer known for substantial tactical-inspired folding knives. His collaboration with North Mountain Blade brings elements of that design language to a production model.
The BBNM features a broad blade, angular lines, and a pronounced handle profile. These characteristics distinguish it from traditional pocketknives that typically favor slimmer blades and simpler proportions.
North Mountain Blade describes the 2522-DT as having a flat-ground tanto blade. This model’s angular tanto profile has a distinct transition between the main cutting edge and the edge near the tip.
That geometry can be useful for controlled cutting tasks, although it requires additional attention when sharpening the transition between edges. Blade shape alone does not establish superior performance across different materials.
North Mountain Blade lists a blade length of 90 mm (3.54 inches) and an overall length of approximately 8.27 inches. This places the BBNM firmly in the full-size folding category, making its dimensions an important consideration for daily carry.
Titanium Handle and Frame-Lock Construction
The BBNM uses a titanium-alloy handle with textured surfaces intended to provide grip. Titanium offers corrosion resistance and a favorable strength-to-weight ratio, although the complete knife still has noticeable weight.
At a manufacturer-listed 144 grams (about 5.1 ounces), the BBNM is heavier than many compact everyday-carry folders. Buyers accustomed to lightweight pocketknives should consider whether that additional weight suits their routine.
The knife incorporates a frame lock, which uses part of the handle structure to secure the blade when opened. This arrangement integrates the locking component directly into the handle rather than relying on a separate internal liner.
A properly engaged frame lock helps resist unintended closure during normal cutting. However, the mechanism still requires appropriate handling and periodic inspection.
The listing also describes a flipper-style opening system that allows the blade to be deployed without gripping its cutting edge.
An included pocket clip provides a dedicated carrying position. Handle thickness and surface texture may affect comfort depending on pocket placement and clothing.
Blade Material and Specifications
North Mountain Blade’s official product page for the BBNM 2522-DT Shadow Edition specifies a DLC-coated CPM-3V blade measuring 90 mm (3.54 inches) long and 4 mm thick. The manufacturer lists an overall length of 210 mm (8.27 inches) and a weight of 144 grams (about 5.1 ounces), with a titanium handle and titanium pocket clip.
Practical Considerations for Everyday Carry
North Mountain Blade positions the BBNM for everyday utility and outdoor activities, including camping and hiking. Its folding construction makes it portable, while the pocket clip provides a way to keep it separate from other carried items.
The knife’s blade length may appeal to people who prefer larger cutting tools. However, routine tasks such as opening packaging or cutting cordage generally do not require a folding knife of this size.
The frame lock and pivot mechanism also require periodic inspection and cleaning. Dirt, moisture, and repeated use can affect moving components, making maintenance part of responsible ownership.
Buyers should also consider local regulations governing knife possession and public carry. Restrictions can vary by location, regardless of a manufacturer’s intended uses.
Who Should Buy the North Mountain Blade BBNM?
The North Mountain Blade BBNM 2522-DT is intended for buyers who appreciate Duane Dwyer’s design approach and prefer full-size folding knives with titanium construction. Its tanto blade, frame lock, and pocket clip provide the core features expected from a substantial utility folder.
People who prioritize minimal weight or only need a knife for occasional packaging may find a smaller design more appropriate. Buyers should confirm that they are ordering the 2522-DT Shadow Edition, as specifications differ across BBNM variants.

At $380.00, the BBNM 2522-DT Shadow Edition is an enthusiast purchase, not simply a way to get packages open. The draw is the combination of Dwyer’s angular tanto profile, titanium construction, and a full-size folding format. If that design is what caught your eye, those are the details worth weighing against the price.
