This knife is similar to the nylon fiber knives, but this one is made from hard ABS plastic. It is very strong, and has the added bennifit of a clip on the handle which allows you to hold the unit securely in your pocket or purse. The serrated edges allow cutting when used in a sawing motion, but like all CIA style knives; this is not really sharp. 7-1/4" long with a 3-3/4" blade.
