Question: Has anyone taken this thru an airport I fly alot and am looking for a pen that will clear thru TSA
Document: This is a heavy duty pen and writes great but looks like a weapon. A TSA would not allow this pen to be brought onto an airplane. If you are looking to do so I would recommend getting something else. Overall I am very happy with it though and would recommend it to anyone looking to purchase a tactical pen.
I still don't recommend it over the S&W; for an every day use pen. But if you just looking to whip some ass I would use this over the S&W; any day
Super cool looking pens. I had the Uzi labeled one but lost it after about two years of carrying it every day. So I ordered this off brand one and as I suspected it is the exact same thing just $10 cheaper. Cool thing is that the Space pen refills fit!
It was a good deal and was just what I was looking for to carry for self defense when a gun is not an option.
It is the screw type, which i personally have no major beef with, though a time or two it was a bit of a distraction. I think in all real life instances a more rapid one handed deployment of the writing tip would be preferred, if nothing more than the item seems a bit sinister to most onlookers. I had a couple people remark about it and one want to hold and feel it. I am happy with it as a defensive tool in my concealed carry defensive tool kit; but will be looking at others because of the pen issues.
When your talking lives here, a good smack of the window breaker in the head or face will EXTREEMLY HURT someone weather it be in the temple you could kill the person, anywhere else, extreem pain and possibly blood to get in their eyes or just stunn and scare them enough for you to get away. You can use the pen side to jab in neck or armpit, ribs you name it, it'll hurt. Then run!Then when using it as a pen, it's a lot lighter than others I've bought so my shirt pocket won't always be tipped open or looking like I have a brick in my shirt pocket!
Good service, reasonably priced. Appears and feels like a pretty good defensive implement. Did not see availability of refills though. I have not taken it apart to see what kind of refill it uses since i am traveling and have not gotten around to it yet. Will have to do that as soon as i can because as a pen it kinda sucks. Day one it wrote like it was running out of ink, and every time i use it i have to do that scribble thing to get the ink flowing again.
This pen is a knockoff of the real thing, good it is. The only thing wrong with this pen is the ink cartridge which was leaking when I received it. However, changing it for a real cartridge, the space pen cartridge is leveling up and worth the few extra dollars. The pen is weighty which is a good thing; keeps would be forgetters to return your pen. The pen is intimidating too, I had my original taken from me at Heathrow. The pen works well with gloves on too, especially with the space pen cartridge as an enhancement.
Really like the pen...i DO prefer the Bud k ONLY because of the pull off  cap..I keep the tip of the pen on this one just inside of the opening when i use it so it doesnt tske too many turns to have tip out enough to  write with.....very pleased and have gotten alot of compliments!
This is clearly a weapon and I don't think you're going to be able to get this 'writing device' onto a airplane. It's about as discreet as a full size 1911 pistol and even a 1st-week TSA agent is going to object to this thing going on board. This premise is going to go unproven though because I'm not even going to try to pass this through security; I don't need a Homeland Security Interview and miss my flight. I'm probably wouldn't even hand it over to a client to sign a document with.
Answer: yes
