My pen is the one from Benchmade. The aircraft grade aluminum pointy-ended jobber. Check out the benchmade site or knifecenter.com.
I've gotten it successfully on airplanes too. I merely pull the cap and switch ends so the cap covers the pointy part and put it in my briefcase with the other pens. Run it through x-ray.
If it is questioned, it is in fact just a pen. And it isn't technically "sharp". Though it could be sharpened in a pinch. But its a fine skullpunch. Or insta-trach tool, as needed.

Is it something like the object to the left of my eyeglass case? This is part of my EDC. The pens go inside side pockets, while the front pocket holds a comb, and some forceps, useful for getting small screws from deep within PCs. My ordinary pen is a Rotring with pencil, stylus, pen, and highlighter. When I learned they were discontinued, I bought two more spares on eBay.
Currently, I have these two GG&G "discreet tools" in my briefcase.
One has a titanium tube, and the other carbon fiber. The only testing I've put them through is as icepicks, and they work quite well.
Oh, BTW, I found your review of the ASP lightweight baton quite helpful. I got one, and it goes in my pocket whenever I leave the house. This being Michigan, I'm sure it's a felony to merely possess one.
