Benchmade offers several spring assisted knives, but none like the Boost 590. This knife has a satin drop point CPM-S30V steel blade. The handle is black Versaflex with a gray inlay. The blade can swiftly be deployed by flicking on the thumb stud. This knife does come with a safety lock on the spine of the handle. Dual Durometer handles greatly increase grip performance while maintaining strength on this fast-action assist. Made in USA.
