Single Edge, Automatic Deployment, No Fumbling Required
This knife does one thing well: it gets the blade out fast and puts it back just as cleanly. The single-edge design makes it practical for a wider range of everyday cutting tasks — food prep, box cutting, utility work — while still delivering the fast deployment that makes OTF knives worth carrying. At 9 inches overall and 5.5 inches collapsed, it’s a full-size knife that doesn’t take up excessive space.
The premium steel holds up to regular use, the black finish resists cosmetic wear, and the mechanism stays consistent over time. If you’re looking for an automatic knife that covers both utility and tactical applications without the legal complications that double-edge blades can carry in some jurisdictions, this is the practical choice.
Who This Automatic Knife Is For
Everyday carry users who want faster access than a folding knife provides — and live in areas where single-edge automatic knives are legal — will find this a genuinely useful addition. The 3.5-inch blade handles most utility tasks without being excessive in size.
Knife resellers and wholesalers looking for a reliable single-edge automatic at a competitive price will find this moves well alongside tactical gear and EDC accessories. It photographs cleanly, the specs are honest, and it delivers what buyers in this category expect.
Collectors rounding out an OTF selection will appreciate having both the single and double-edge variants available. The slightly more compact profile of this model gives customers a meaningful choice rather than just a cosmetic variation.
Is This the Right Choice for You?
Choose this OTF single-edge knife if you want:
- Instant one-handed blade deployment for utility or tactical carry
- A single-edge blade with broader legal acceptance in more jurisdictions
- A compact 9-inch overall profile that fits most carry setups
- A clean, honest wholesale knife with strong everyday carry appeal
Consider something else if you need:
- A double-edge blade for symmetrical cutting — see the ST-AK-103 version
- A blade shorter than 3.5 inches for jurisdictions with strict length limits
How It Actually Works
The mechanism is the same spring-loaded OTF system used across this product line. A sliding button on the handle spine sends the blade out through the front of the handle on forward pressure, and retracts it cleanly on a backward pull. No rotation, no wrist action, no two hands needed. For people who carry a knife as a working tool, that kind of consistent, repeatable access matters.
The single-edge blade is sharpened on one side, which makes it more intuitive for everyday utility tasks and somewhat easier to maintain with standard sharpening equipment. The 3.5-inch length hits a practical middle ground — enough reach for real work, compact enough to carry without attracting attention.
At 0.7 lbs and 1.25 inches wide, the knife balances well and carries comfortably. The narrower profile compared to the double-edge version makes it marginally more pocketable for daily use.

Frequently Asked Questions
What makes a single-edge OTF different from a double-edge OTF?
The single-edge blade is sharpened on one side only. That makes it more practical for everyday utility tasks like cutting rope, breaking down boxes, or food prep — tasks where a double-edge isn’t necessary. It also tends to have somewhat broader legal acceptance in jurisdictions that regulate blade type, though you should always check local law. The double-edge version (ST-AK-103) offers a longer blade at 3.75 inches and a slightly wider handle profile.
How reliable is the OTF mechanism over time?
The spring-loaded mechanism on this knife is designed for consistent, repeatable deployment. Keep it reasonably clean, don’t force the button against resistance, and avoid deploying it against hard surfaces. With normal use, the mechanism maintains its function reliably. Like any spring system, occasional inspection for debris or wear is good maintenance practice.
Is this knife legal to carry in my state?
Automatic knife laws vary significantly by state and municipality. Some states have no restrictions on OTF knives, others restrict blade length or require permits, and some prohibit automatic knives entirely. We sell this product for lawful purposes only. Check your state’s knife laws and any applicable local ordinances before purchasing for carry or resale.
Can I sharpen this knife at home?
Yes. The single-edge steel blade can be sharpened with standard whetstones, ceramic rods, or pull-through sharpeners designed for straight-edge blades. The single-edge design makes home sharpening more straightforward than a double-edge blade. Maintain the factory bevel angle for best results. Premium steel takes and holds a reasonable edge with regular maintenance.
