Safety Technology OTF Automatic Knife ST-AK-104 – Single Edge 3.5-Inch Blade, Out The Front Deployment, Premium Steel, Belt Clip, Glass Breaker Tip, 9-Inch Overall, 5.5-Inch Collapsed, Black

An OTF Built for Everyday Practicality

The double-edge OTF appeals to a specific user. This single-edge version is built for a wider range of people. One cutting edge means you can rest a finger on the spine for control, use it for standard cutting tasks without overthinking blade orientation, and handle it more naturally if you’re transitioning from a traditional folder.

The belt clip and glass breaker tip signal what this knife is really for: daily carry as a practical tool, not a specialty item.

Who This Knife Is For

People who want OTF deployment but prefer the safety and familiarity of a single-edge blade. Daily carriers who value the belt clip for consistent positioning. First responders, drivers, or outdoor users who find the glass breaker tip adds genuine utility.

If you’ve been curious about OTF knives but felt the double-edge models were more specialized than you needed, this is the more approachable version of that same mechanism.

Practical Features That Earn Their Place

The belt clip isn’t an afterthought. It positions the knife for consistent draw — you know exactly where it is and which direction it faces. For people who carry a knife daily, that consistency matters. You develop muscle memory for accessing it, which means less fumbling when your hands are full or you’re working in poor conditions.

The glass breaker tip on the handle base serves a straightforward purpose: breaking tempered glass in vehicle emergencies. It’s a hardened point that concentrates force on a small area. Whether you work around vehicles, drive regularly, or spend time in situations where vehicle egress might matter, having that capability integrated into a tool you’re already carrying makes practical sense. It’s not a gimmick when it’s built into a knife this substantial.

The single-edge blade offers a flat spine for thumb placement during controlled cuts. This gives you significantly more precision and control than a double-edge profile. For most cutting tasks — opening packages, cutting rope, slicing materials — a single edge is all you need and safer to handle.
