I’ve handled several models, and the XXV Doughnut OTF Utility Knife with 20 Blades stood out.

How Does a Double Action OTF Knife Function?
A double action OTF (Out The Front) knife operates by using a mechanism that allows the blade to be deployed and retracted with a single action, typically via a switch or button.
- Deployment Mechanism: This mechanism is responsible for pushing the blade out of the handle when the button is pressed. It often consists of a spring-loaded system that allows the blade to extend rapidly, making it ready for use in a quick motion.

This device engages the spring mechanism, allowing for a smooth and swift deployment and closure of the blade, making it user-friendly and efficient for one-handed operation.
- Blade Locking System: To ensure safety during use, a locking system is incorporated to secure the blade in the open or closed position. This mechanism prevents accidental deployment or closure, providing confidence that the blade will remain safely in place during use or transport.
