Review on GP 1945 Bolt Action Pen PRO: A Multi-Functional Titanium EDC Pen With Rescue Whistle, Glass Breaker And Survival Gear For Camping, Self Defense, And More - A Better Alternative To A Pen Light by Donald Phi

The only one I've bought is the Titanium.Extremely sturdy pen. One of those every day items in my pocket. I've used mine not only for all those writing tasks, and the bolt action is a pure joy to simply fiddle with. But, I've also used the fact that this is a very rugged pen for chores that it was probably not designed. Things like resetting the safety valve of a propane tank when a Boy Scout does not attach the regulator properly. Prying and poking things that a stick just can't without breaking. I also love the fact that Titanium does conduct heat as well as other metals, so you can write with this in the cold and not find your hand frozen.Very useful, very sturdy.My original was from a Kickstarter. The one I bought here on ebay is going to my God-daughter as a graduation present. Hopefully to be used for proper college things, but it will also serve as a nice tool to explain the meaning of "no" to a overactive date.
