This Rampage Assisted-Open stiletto from United Cutlery opens with the speed of high-end knives at a tenth of the price. The 4" stiletto point stainless steel blade is razor sharp and offers a backside spur equipped with a Blackie Collins assisted-open mechanism for speedy, one-handed opening. The slim profile is hardly felt in a pocket, but when the blade is deployed, it transforms into a fearsome self-defense knife. 4" blade, 9" overall.
