Item appears to all intents and purposes to be a regular pen, however, a simple twist will separate it and reveal a thin 2.5 in blade that is better suited to sharpening pencils. Nevertheless, in an emergency might provide a deterrent or if used properly could inflict enough damage to ward off an attacker. It is primarily a knife so the actual pen part is only adequate with ink drying up intermittently.

I love it

OMG I loved it at first when I first got it. It writes looks and feels like a typical pen but it's hidden knife inside. I bought it for protection when I have to walk home alone and trust me when I say every woman needs something like this in their life . It's so easy to use and hold.

cool!!

Overall a good product. Don't expect it to be incredibly sharp, it wasn't built that way. Great as a fun and unique letter opener or conversation piece. Functions as a real pen and doesn't have bad ink. Don't drop it.

I loved this pen. It works as a real pen but has a cool twist to it. It wrote well. Only thing is I went to put it in my shirt and dropped it once. Well when it hit the ground the tip broke off. I was highly disappointed. It's a all around good pen... Just don't drop it.

I bought one of these thinking, "For the price, I shouldn't expect much." I was shocked at how nice it looked when I opened it. The only reason I give 4 stars instead of 5, is the issues I have with the blade. I don't like the edge on it. It's sharpened only on one side, and the curve is way too steep. You would have to sharpen it all the time. The point of the blade however, was SUPER sharp. So that's cool I guess. I also didn't like the clip on it. I carry this pen in my pocket and after only a few times of wearing it, the clip became really loose and shaky. But what can I say, It's only 4 freakin' dollars. Buy one.

At first i was sort of hesitant of ordering this but after i got it i was very satisfied. its a really small one inch blade that fits into the pen. the pen also works as a normal pen. In the end its a cool tool to have around the office and i see myself getting more in the future because of the low price

this pen knife is very good! not only the design.. I also liked about the double function with pen and knife I recommend you guys to buy this one thing, don't try to put this under the water or it might get broke anyhow, buy this I'm pretty sure you'll love it! hahaha

AWESOME...I got this for my dad for fathers day and he loves it,was smaller than I thought it would be but it was built extremely well... I even dropped it to test andys review and it was still built to last!!!!! thanks budk
