Barry's defensive stylus is a bit over 6" long and is made from G-10 with a sharpened titanium core. It's available in different color options with a clip for attaching to the pocket or any where else. There are quite a few defensive stylus designs out there but I think Barry's is particularly noteworthy and the best one I've seen as of yet. First Barry's design doesn't look like a weapon. It's very "happy" looking with the alternating red and blue G-10. Some would probably think that it's downright cheap looking, which is good. It should look like a .98 cent Wal-Mart pen. To me that's a huge part of the appeal, in that it could be easily glanced over if given a cursory look. Look at the next picture and note how Barry's stylus blends in nicely with other writing tools.
