Krate Tactical KRT Sentinel OTF Knife

The Krate Tactical Sentinel is the large-format OTF in the Krate lineup, deploying a 3 3/4-inch D2 steel double-edge dagger from a blacked-out aluminum frame at 9 1/4 inches overall. At 244 grams, the Sentinel is a substantially larger and heavier OTF than the standard Krate line, built for operators who want a full-size, full-weight automatic with serious presence in the hand.

• Dual-action thumb slide: One-handed deployment and retraction on a single slide.
• Ceramic tip glass breaker: Built into the pommel for emergency situations.
• Tip-down deep carry pocket clip: Secure carry despite the larger frame.

• Lifetime warranty from the manufacturer (excludes loss or theft).

Why It Matters in the Field

The Sentinel is built around a different use case than the standard Krate line. The 3 3/4-inch double-edge dagger is a dedicated tactical blade, not a utility cutter. The 244-gram weight gives the knife real presence in the hand and on the deploy. The all-aluminum frame and blackout finish strip away the visual cues and run a clean professional profile.

For operators who want a full-size automatic — closer in stature to a premium production OTF than to a compact EDC — the Sentinel slots into that role at a price point well below most equivalents.

FAQ

Is a double-edge dagger OTF legal where I am?

Double-edge daggers carry additional restrictions in some jurisdictions on top of the general automatic knife laws. The customer is responsible for verifying state, county, and municipal regulations before ordering. Active-duty military and LE personnel are typically exempt from most restrictions.

Does it ship to APO/FPO addresses?

Yes. tacticaledge.com ships free to all APO and FPO addresses. Automatic and double-edge knives may carry additional shipping restrictions overseas.

Can I carry this concealed?

The deep carry clip is included, but at 9 1/4 inches overall this is a larger knife than the standard Krate line. Concealment under a duty shirt or cover garment is possible but the knife will print more than the standard 8-inch OTFs.

How does D2 steel perform on a double-edge dagger?

D2 at 58HRC holds two edges as well as it holds one. It is harder to resharpen than stainless but offers longer edge retention between sharpenings.

What does the warranty cover?

Krate Tactical backs the knife with a lifetime warranty, excluding loss or theft.
