**FOR A SPECIFIC BRAND NAME SPRING ASSISTED KNIFE, PLEASE CLICK ON "KNIVES BY BRAND" AND THEN GO TO THAT BRAND'S SECTION.
Spring assisted opening knives are the hottest category in the knife business right now. Like automatics, they incorporate a spring to rapidly open the blade, but they differ from automatics in that a manual pressure is required to deploy the blade, such as pushing on a thumb stud or protruding part of the blade, as opposed to pushing a button, as in automatics. This difference makes them legal to own even in areas where switchblades are illegal.
