cool and sharp
"one of my favorite things to have laying around - it's cool to surprise ppl and if I ever need something sharp and lethal it's always hidden in plain site"
Exactly what I was looking
"Exactly what I was looking for shipped fast"
Ink Pen Knives
"I purchased both the plain and serrated blades. And I'm very happy with both. As a matter of fact the plain blade has already come in handy by protecting me from wild envelopes. I'm positive that if I didn't use the pen knife to open those envelopes I got in the mail, I would have most likely gotten a paper cut. I'm waiting for a parcel, so the serrated blade can protect me as well. 😁"
about right
"you get wheat you pay for - pen works, blade is sharp - smaller than advertised - bee good letter opener"
Pen knife

#2
"This is my second one and like the first is excellent, the first got dropped on its point and that ruined it. Wish refills were offered."
Pretty good
"For 7 dollars it was pretty good. Not really any complaints, except the blade looks different than the picture, it's a lot more thin."
pen
"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."
This is one fine pen
"Reviewed by Cody McCullough on July 21, 2016 I reseved my pen yesterday and I had high expectations, and it passed all of my test. The blade is sharp, easy to carry, and it is most exquisite for wrighting. If you are looking for a great tatical pen then this is it."
