Switch Blade Knife - 7610 | 7679 | A39 | Knuckle Buster | Single Blade | Wolf Pattern | Double Side

Usage Instructions

Deploy the ONT A39 by pressing the thumb lever located on the side of the handle; the blade will spring out instantly, ready for defensive action. Carry the tool in the provided nylon sheath or attach it to your belt using the built‑in loop for quick access. The glass‑breaker tip can be used to shatter vehicle windows or emergency exits when rapid egress is necessary. In a lethal protection scenario, strike at vulnerable areas such as joints or limbs to neutralize the threat efficiently.

Safety Guidelines

Never point the blade toward anyone unless you intend to use it for defense. Keep fingers clear of the deployment mechanism until you are ready to engage. The tool is intended for lawful self‑protection and animal deterrence only; misuse against unarmed individuals may result in legal consequences. Store the device out of reach of children and in a secure location when not in use.
