I ordered a couple of these a couple weeks ago and put one on each of my key-sets. I'm very impressed with the quality, it's a very well-made little tool. The carabiner function is a great idea. The gate is small and stiff, but I think that's pretty much what you'd want.
I think it's well worth the price, but it's not perfect. I'm planning to ease the corners all the way around to make it more comfortable to carry and use. Never done that with Ti, but I assume I can use a stone/file/sandpaper. Anyone with experience I'd be grateful to hear about it.
I'm not sold on the utility of the carbide glass breaker. Not sure I could get a good enough grip on the tool to make it work, and if I did the sharp prying tip would be buried in my palm and I can easily see it cutting my hand. Plus in an emergency situation (car in the water, need to break a window) with a full-on adrenaline dump I think it would be tough to peel back those tight little O-rings to expose the carbide.
But again, overall it's a nice piece, with the cool factor/strength/lightness of Ti, at a reasonable price. I'll probably order a few more to have for convenient man-gifts. Now I'm just looking for a chance to actually use it.
ETA: "Access Tool" sounds more like a prybar you'd use to open a door. Not the most accurate name for a 3.5" keychain tool.
ETA: The region where the carbide tip is would be a great place for a screwdriver tip.
