This is one of the smallest knifes I could find. I wanted a small streamlined knife for hydrodamism and also a short knife to wear on my weight belt that would not push against my hips. In these respect the knife was great, however the locking mechanism is hard to open with only one hand, and worst the locking mechanism sometimes OPENS BY ITSELF! I lost the knife after a couple dozen dives. I still like the knife but would drill a hole in the handle and attach a string not to lose it...
