Two thing of interest to me in the TAD Gear Tools are size and titanium. Being titanium they are supposed to elude certain metal detectors - tho I suspect that they would show up fine on X-ray. But dog-tags didn't ring the bell when I last flew so ... In any case, I sharpened the long edge of a p38 for use in my PSK and find that it is a fine edge for what can be fit into a PSK and it has the added advantage of being a p38 as well. I keep the sharpened handle piece of the p38 together with a safety razor in the cardboard protector that came with the safety razor. Gives me a really sharp fine work sharp that dulls rapidly and a sturdy sharp with more gripping surface and more durrable edge in a very economically sized PSK package. Other in such space confined situations I wouldn't find a use for such small sharps. When camping I have my PSK as well as my Bushman and my Leatherman Wave. When around the office I have my Leatherman Wave and a small Dakota multitool about the size of a micra that has a LED light built in.

I'm all about redundancy and multi-function when it comes to tools.
