Well....not counting the Leatherman Wave and the Leatherman Micra that is on my key chain...those are in fact knives, but more or less things like screwdrivers and pliers that just happen to have a blade. I carry the Leatherman Wave because it has sooooo many little tools and the sheath carries a pen, lighter,USB drive, etc. I can swap out the pen for the Surefire 300 Titan flashlight, but that's on my keychain most of the time anyway. Considering getting a slim butane torch to put in the Leatherman holster/sheath.
Well, the Military is on me no matter what. That is and always will be my primary. The PM2 that I just recently got has been more than impressive....still a bit small, but great for light jobs and I like it a lot because it is very much like it's bigger brother, the Millie. I have great respect for the Millie because it functions well as both a SD tool, and a multi purpose tool. And now that I carry the Leatherman Wave, I have no need to carry the serrated Millie...that will stay in my car God forbid. And if for some reason I can't reach it in a wreck, I can always reach the serrated blade on the Leatherman. And lastly, my neck knife. When driving....the tools and blades on my waist are not the easiest to deploy with speed. So, the Cold Steel push blade on my neck will work.
Not to mention the 1911 on my side or the G27 as my BUG....I think I am ready for whatever hits the fan. Yes, I do carry 3 kinds of different pen knives and a little pointed "cat" head on my key chain which serves as a pair of pointed brass knuckles. Truth be told....I once carried more gadgets, but when I was younger...they were just for fun. Now, I carry what I fear I might have to use one day. I try not to mix things up that often....I don't want my mind to spend time thinking about what is located where. I am often in not so friendly neighborhoods....the last thing I want to do is shoot anyone, so if I can leave and get out of there without having to do so.....job well done. What I have in my car is a story for another thread. I will say this though....I'm glad I decided to pick up a PM2. Great little knife. Not nearly as confident with it compared to the Millie, but none the less...it serves it's purpose. And lastly....my Karambit. I have had a great deal of training with one...and I think I would pull that one out in a SD situation. Not only because it has a "wave" on it and I can deploy it faster than anything else I have on me, but used correctly....I've seen what kind of damage that little monster is capable of. Not practical as a tool, but as a SD device....VERY VERY effective in the right hands.
