Review on TAKEFLIGHT Tactical Pen Survival Gear – Aircraft-Grade Aluminum Tactical Multi Tool – Rugged, Lightweight EDC Pen Survival Tool With Glass Breaker - Cool Gadgets For Men - Father'S Day Gifts For Men by Chris Hall

This is a decent tool for the price, and it writes well. There are a few issues that should be known. The mechanism inside the cylinder that holds the ink cartridge and threads the pen together is poorly made. I took the pen apart straight out the box to see how to change the cartridge and the mechanism shifted making it hard to put back together. I had to remove the window punch to push the mechanism back in place. Another thing I noticed is if you move the clip it will loosen the window punch. Again for the price that it is, it's decent.
