This Halo V knife has a satin finished clip point blade with a plain cutting edge. The 6061-T6 aluminum frame and charging handle are black anodized and the hardware is bead blasted. This knife includes a fitted sheath with belt loop attachment system.

The Microtech Halo V knives are big, powerful, and look great. The biggest difference between the Halo V series and the previous models is the size. At almost 11" the Halo V is a big knife with a big blade. In addition to being long, the blade is extremely thick. To ensure the best blade/handle ratio the tips on these knives come right up to the top of the handle, so don't drag your finger across the blade's exit point! The action on these is fast, they hit hard, and the lock-up is excellent.

The steel on this knife is N690, but some Halo knives have been incorrectly marked "M690" on the blade.

Just speechless

This knife doesn't look like it should be worth as much as it is, but it definitely feels like a quality knife. The handle is perfect in every way, the anodization feels amazing and the jimping is super grippy without cutting into your hand. You have plenty have room for your hands. I have smallish hands, and I'm able to get both hands on the handle, (although it is extremely cramped and impractical if you try to do that) The blade steel on my halo is elmax, and while this is a grail knife for me and I never really use it, I have had very good experiences with elmax in the past.

The blade looks stunning, and is the sharpest knife I have gotten from the factory, better than the benchmade customs my friend has. The blade is milled out extensively, giving it an amazing look, and while I usually DESPISE writing on the blades of my knives, I really like the way the writing looks on here. I guess it keeps the knife from looking too plain for me.

Now for the things that I don't like about this knife. I ordered my halo just when they went from textured buttons to bead blasted buttons, so I was a little bit disappointed at that, but I've grown to like it. The other thing about this knife is that on the top and bottom of where the writing is on the draw bar, the anodization has already started to rub off, obscuring the manufacture date and S/N. These things don't really bug me, but its something to consider when spending hundreds of dollars.
Otf goodness

This was a grail knife for me. Microtech can have long droughts of knife production, and they can become very scarce. I grabbed my Halo as soon as it became available. I have not been disappointed. It fires hard, locks up every time, and has almost no blade play. Admittedly, there is a small amount, but it is so tiny, I don't even notice. That is typical of almost every otf knife in existence. This knife delivers.
