Assisted Opening Knives

Assisted opening knives are often time called a spring-assisted knives. So, this is a knife that springs open only after the blade is slightly pushed open with force.

It is unlike the switchblade where nothing holds down the assisted opening knife when it’s in the closed position. So, as the user begins to open up the blade with a thumb stud or flipper lever, which has some resistance, the spring or torsion bar catches the knife and propels it open where it locks into place. In other words, the natural position of the spring assisted opening knife is closed. There is no pressure being exerted upon the blade, and there is no button to push.

Simply put, if there isn’t anything blocking the blade and it stays closed, the knife is an assisted opener. Because of how the assisted opening knife is made, it is legal in all 50 U.S. states
