I have one and I love it!
I'll start with the overall construction: very pleasing and of high quality. The attention to detail and design is really amazing for a knife this inexpensive. If it were made in the USA instead of Taiwan it would cost twice as much easily.
The materials are very nice and time proven: hardened aircraft aluminum handles (anodized OD green) and an AUS-8 blade. Mine came extemely sharp out of the box (not quite as sharp as my Spydercos but sharper than my Benchmade came new). I like the bead-blasted finish (almost a frosted finish really), and it's a welcome break from the bright reflective Spydercos that I usually carry.
The clip: bead-blasted and non-glare too, it looks very nice against blue jeans. It was alittle too tight when I first got the knife so I bent it out just a hair and now it's just right. It's a good strong clip and designed better than alot of clips on high-dollar knives.
The handles: Although they're aluminum they're textured very nicely, and are certainly non-slip. The diamond texture is graduated from very tiny to larger and is very pleaseing to the eye as well as the hand. The handle shape looks alot like a Terzuola design to me (compare the handle shape of the Harsey Air Ranger to the Spyderco Starmate and you'll see what I mean). It is very comfortable in the hand in a variety of grips.
The blade shape and design is good for all-around utility and is larger than it appears at first (just under 3.25").
The liner-lock is easy and simple and seems to work just fine.
And if you think it's not that strong consider this:
I was curious about the handle and lock strength of this knife and my FRN Endura, so I did a little test of my own.
I hammered my Spyderco Endura, my CRKT M16, and the Air Ranger through about 2.5" of hard cedar (I wrote a review and posted it at the time). I knew I was risking permanent damage to all three knives but I had to know.
Well, they all came out just fine and apparently unharmed.
It's not the most elegant or finest knife around, but I am very impressed with the bang-for-buck, and the more I use it the more I like it.
It's one of the most comfortable knives I own and the only one that gives my Spyderco Endura competition for EDC status.
Good luck,
Allen.
