Question: How does the writing tip retract? Do you twist it to retract it or is it a push button on end?
Document: This one came in last place among it's peers. I'm sure you could do some damage with the end (I bought them as rugged pens, to write with. Not fight a war with... Afghanistan was eating through my pens though...)It's hard to get the writing tip out (Twist the end, instead of pull cap off or click). The ink it comes with is retardedly difficult to write with, and the pen just doesn't feel nice.
I could not give this pen five stars for the following reasons:  There were small imperfections in the machining of the pen; although none of them would affect performance. Clearly a quality control issue. There was a large burr at the tip where the pen comes out, but again, it does not impede performance. On most twist type pens, it takes about 90 to 180 degrees of turn for the pen tip to extend or retract.
This is not a bad pen for the price, but there are some minor issues. The ink cartridge fits the tip quite loosely, which lets the tip move a little while writing. This can be remedied with a little clear tape. The method used to retract the tip is simply to unscrew the body far enough. This is OK, but leaves a loose fit between the two parts of the body. The o-ring on the body helps the fitment and keeps it from loosening too much.
As a matter of fact unless you do a few circles before every use and press quite hard, it won't write reliably at all. Next, the pen is a "twist" style, but it take a good 5 twists to get the tip exposed or covered. In other words it is a very slow and tedious process - not something I want in a writing instrument.
I found the pen to be entirely appropriate for its intended purpose. As others have commented the need to unscrew it 3 revolutions (about 5/32nd inch) to retract the pen is somewhat off putting at first. However it needs to be sturdy and immediately useful so a cap or push button (as others have commented) would, I am sure, limit its strength for tactical purposes.
It's a big, clunky pen and the ballpoint does not retract. You can't click it or twist it. It will absolutely make a better self defense item than a regular pen, so might be decent to keep in a car or for a woman to carry when walking alone at night, but it just didn't impress me much.
The pen is well made, and I like that you can rotate the body to retract the writing piece. The negative is the pocket clip is so strong it is difficult to clip on your pocket. Overall I really like the pen.
this piece is neat, i use it for writing all the time! I havent been attacked by rabid muslims or nazis yet, so the real business end of this thing remains untested for now.
Had retractability problems with the writing end, and was not satisfied. Remember, a lot has to do with personal preferences when making your purchase of this type of instrument. I found that in the end like with a lot of things, time and research was the best tool in making the overall decision and final acquisition of what I needed.
I bought this not realizing it was sold by Rothco. Had I known I would have NEVER purchased it.The pen doesn't retract or is defective and doesn't. A pen tip that remains permanently exposedIs next to worthless for me. Wish I would have never bought this!
Answer: yes
