Microtech Halo 3 OTF Automatic Knife

Reviewed by corwin99 on February 5th, 2013

Ladies and Gentleman, what we have here, is a very rare and collectible piece from Microtech. It is a 1999 Vero Beach period Microtech Halo 3 OTF Automatic, one of the legendary knives that put Microtech on the map, and it is in mint condition. I was giddy as a school girl when a friend approached me with the opporunity to procure this fine piece of tactical cutlery history.

One of the things you might notice about this older Halo 3, if you’re not familiar with the older Microtechs, is the screws are Torx! The knife features a black coated 154CM Stainless Steel tanto blade with the familiar notch on the spine which allows the firing button to recess into it and keep the knife closed. The firing mechanism is fast and precise, and the charging handle is delightfully well-machined.

Since this is not a dual action OTF, you have to depress the firing button, and pull the charging handle back in order to close the knife. Single Action OTFs are usually more reliable, fire harder, and have a better blade to handle ratio than dual action OTFs.

The handle is precision machined 6061-T6 aluminum, with a Level 3 hard annodized finish. The surface is satin finished with no pocket clip and is very slim. Vertical and horizontal grooves are machined on the sides to provide a bit of traction, and gives the blade a nice feel in the hand.

Overall this is a collector’s piece that I doubt you will see too many of. The Halo 3 remains a key part of the Microtech history and evolution of the OTF Automatic knife. If you can find one, its a great collector’s piece.
