D-Link?
Brad, are you a climber?
That looks like a D-link around your shifter.
The "tire checker" may, on the one hand, be "prudent" for someone who believes he's at risk of carjacking, but on the other hand it is almost certain to draw frowns from the constabulary.
While it may have originally been made to thump tires, it bears an unfortunate resemblance to a police nightstick/baton without the additional grip. Of course, if your jeep has a 12-inch lift kit and really large truck-class tires, then maybe a thumper would pass muster.
I'd find it a place of honor on your wall, and replace it with something like a thick, heavy ruler.
I have a yardstick, a green plastic three-foot shaft with a cross section of about an inch. Trust me, you wouldn't want to be whacked by that thing. I know that I, personally, didn't enjoy it at all.
If you find a heavy plastic yardstick, and cut it down to 24 or 18 inches, maybe rough the grip and smooth the corners a bit, you would have a relatively innocuous (yet robust) length of stuff that could be used to clear snow and ice from fenders, thump tires, or even rap the knuckles of a carjacker. Oh, and you can measure stuff with it, too.
Your stick is certainly handsome, but I'd leave it at home.
