Here is an interesting tool and self defense weapon. It is called
"The Penatrator." It comes in titanium and carbon fiber with a beveled tip. Comes with a pen cap, to make it look like you are carrying a pen.
This model is the carbon fiber one. This tool is meant for quick and discreet deflation of an air inflated tire. It is hollow and the front part is angled a beveled tip to pierce through the rubber or your attacker.
Here I demonstrate a small air inflated tire being punctured by this tool, the penatrator. It does work to a point, at least on the first time but afterwards I keep on stabbing the tire and it is not easy to puncture it again. Works easier when inflated and the air escapes quickly and quietly through the hollow of the pen.
The sad part, it cracked on the front angled beveled piercing point. You can see a hairline crack on the tip after my demonstration. This tool costs about $40.00 to $50.00 depending where you get it but to me this is not worth it and to see carbon fiber crack with this minimal test is pretty sad and says a lot about the quality of such a tool. I have not tested the titanium model and don't intend to.
In my opinion this tool needs more weight and the price is over rated. It should cost more like $10.00 to $15.00 and I am being nice.
It can be used for self defense but if it cracks under pressure on a tire, then what would happen on a human attacker wearing a jacket, I don't think it would penetrate. So this tool is better to use as a straw.

Here are the stats on this tool:
The PENATRATOR tire deflator is another product in a series of covert defense tools designed and manufactured by GG&G. It is designed to provide a covert tire deflator, or radiator leak initiator as wll as a defensive weapon that can be used in unforeseen emergency situations. In the passive mode, it looks like a large pen but by removing the pen cap a very sharp point is exposed that will aid in dealing with an unexpected threat. Two models are available, one with a 2.6" hollow carbon fiber shaft and one with a 2.6" hollow titanium shaft. Both are extremely rugged, corrosive resistant and lightweight. The hollow shafts provide an effective route to let what's inside--outside! The handle on both models is manufactured from Delrin and is grooved so as to provide a positive grip in the most demanding situations. The tip is protected by a standard pen cap which serves to protect the user when in the passive mode.
Weighing in at only .5 -.75 ounces, the PENATRATOR weapon is an outstanding addition to ones defensive arsenal, especially where stealth is imperative.
