The single-edge OTF gives you the same straight-line deployment as its double-edge counterpart — blade fires forward through the handle tip, retracts the same way — with the added utility of an unsharpened spine for controlled cutting tasks. Premium steel construction, one-handed operation throughout.
- OTF (Out The Front) automatic deployment — linear blade extension and retraction
- Single-edge 3.5-inch premium steel blade with usable spine
- Lightning-fast deployment with equally fast positive retraction
- 9-inch overall open length, 5.5-inch closed length
- Durable black construction, 0.7 lbs
Single Edge OTF: More Versatile Than It Sounds
A double-edge blade maximizes cutting capability in both directions. A single-edge blade with an unsharpened spine gives you something different — a surface you can press against safely, use for scoring or controlled cuts, and brace without concern. For most practical utility tasks, the single-edge geometry is actually more functional than double.
This OTF pairs that single-edge practicality with the speed and directness of front-deployment mechanics. The blade exits straight through the tip of the handle, locks open, and retracts with an equally fast pull of the same slider. All of it happens with one hand.
Who This OTF Knife Is For
This knife suits users who want OTF deployment mechanics — the straight-line extension that requires no lateral clearance — combined with a blade profile they can use for a wide range of tasks. The single edge is more practical than double for general utility work: cutting rope, breaking down materials, food prep in a field setting, and any task where blade control matters more than bidirectional cutting.
At 5.5 inches closed and 0.7 lbs, it carries in a jacket pocket or cargo pocket without issue. It’s a purposeful size — not a keychain knife, not an oversized showpiece.
Is This the Right Choice for You?
Choose this knife if you want:
- OTF deployment with a single-edge blade that handles practical utility tasks
- A usable spine for controlled cutting and bracing
- Slightly more compact dimensions than the double-edge OTF model (9″ vs 9.5″ open)
Consider something else if you need:
- Bidirectional cutting capability — the double-edge OTF model handles that better
- A more compact closed length for front-pocket carry — at 5.5 inches closed, standard jeans pockets may feel tight
How the Knife Performs
The OTF slider sits on the handle spine and operates with a positive, deliberate action. Push forward to deploy — the blade locks open with an audible click. Pull back to retract — the blade returns fully into the handle. The mechanism is spring-loaded in both directions, meaning deployment and retraction are both powered rather than one being manual.
The 3.5-inch single-edge blade is ground from premium steel with a profile suited to general cutting tasks. At 9 inches open and dimensioned at 9″ x 1.25″, the knife is slightly narrower than the double-edge model, which affects how it sits in the hand. The thinner profile suits users with medium hand sizes who prefer a less bulky grip.

Frequently Asked Questions
Why would I choose single-edge over double-edge in an OTF knife?
Single-edge blades offer practical advantages for most utility tasks. The unsharpened spine can be pressed against materials safely, used for scoring, or braced against a surface during controlled cuts — none of which is possible with a fully sharpened double-edge blade. Single-edge blades are also generally easier to sharpen and maintain at home. Unless you specifically need bidirectional cutting capability, single-edge geometry is more versatile for day-to-day use.
How does retraction work on an OTF knife — is it automatic or manual?
On this OTF model, retraction is powered — the same slider that deploys the blade also retracts it under spring tension. Pull the slider back from its deployed position and the blade snaps back into the handle. This bidirectional powered mechanism is a key feature of quality OTF designs. Less expensive OTF knives sometimes use gravity or a separate manual push to close, which is slower and less reliable. Powered retraction keeps one-handed operation consistent throughout.
Is this OTF knife legal to carry?
OTF automatic knives are among the most regulated knife types in the United States. Laws vary by state, county, and city — some jurisdictions permit them freely, others restrict blade length, and others prohibit them for civilian carry entirely. Federal law also applies in some circumstances. It is your responsibility to understand and comply with all applicable laws before purchasing, carrying, or transporting this knife. Always research your specific jurisdiction’s regulations.
How does this knife compare to the double-edge OTF model?
Both knives use the same OTF deployment mechanism and premium steel construction. The single-edge model is slightly more compact — 9 inches open vs. 9.5 inches, and 5.5 inches closed vs. 5.75 inches — and 0.25 inches narrower in profile (1.25″ vs. 1.38″). The blade is 3.5 inches vs. 3.75 inches. The key functional difference is the blade edge configuration: this model has a usable spine for controlled tasks, while the double-edge model provides cutting capability on both sides of the blade.
