The EX01 is the first in the Hogue/Elishewitz Extreme Series Knives. Like every Hogue handgun grip and rifle stock, it is designed to be extremely durable, yet simple, elegant and practical. The EX01 can be an everyday utilitarian knife or a military and law enforcement tool/weapon. To offer the customer their choice of options, it is available in 2 different blade shapes, 2 different sizes and 2 different handle materials in an array of colors. The oversized heat treated pivot , stop pin and button lock as well as oversized washers and integrated spacers are designed to insure the knife's long term durability. Add to this, a manual safety ensures that the lock cannot disengage, giving fixed blade like reliability, and you have an over-engineered tool whose sole purpose is performance. Stonewashed 3.5" blade with aluminum frame. Comes with original box. Excellent condition.
