Document: I expected better quality from a Williams CRKT product. Cap rattles on pen, the schrade pens for less money are a better tactical pen.
I carry it in my pants pocket and it I don't even notice it's there (can't say that about all the folder's I've had) and the clip has lasted through many withdrawals. Usually that is what gets bent first. I can't say how it stacks up against other brands, but I'm very satisfied. Full disclosure--I train with James Williams but if I wasn't happy I would not bother writing a review.
I bought this pen through CRKT website for more than this. I have been very happy. So far I have not had to use the tactical aspects, but as a writing implement it works great. The other day I lent it to a woman at city hall who was having trouble filling out a glossy form. It wrote on the paper just fine. It's not solid enough to punch through a wall, but the pen is designed as a "force multiplier" against a human body.
Answer: no
