First thing that everyone notices about this Microtech is where the button is located...to the side, rather than on top...making it one of the easiest opening OTF on the market. The dagger-like, stonewashed blade makes it the perfect traveling companion for self defense. Like all Microtech knives, this comes with a Limited Lifetime Warranty.
