The New for 2018 Microtech HALO VI (High Altitude, Low Open) is a revamped version of the first ever automatic single action, out-the-front (OTF), knife ever produced by Microtech Knives.. The HALO 6, when deployed, provides the absolute tightest lock up possible. The one handed, fast action open, has fired its way into the hands of thousands of protective agents. HALO’s smooth lines, light weight, and deadly edge, provide a little more than just backup.
To fire simply press the button and feel the Halo deploy with power. To retract, manually pull the charging handle back and watch the blade retract back into the handle. Then press the charger back into the handle and voila!
