WHAT IS A SPRING ASSISTED OPENING KNIFE?
An assisted opening knife uses a spring activated mechanism to deploy a knife blade when a little bit of pressure is applied in opening the knife by the folding method. They are commonly confused with switchblades, but have one main difference. While a switchblade can be opened usually with the push of a button, the user of an assisted knife must apply some pressure to the knife, usually at the thumb stud, thumb-disc or index finger protrusion. Once the knife has been opened, usually between ten and forty degrees, the mechanism will open the knife the rest of the way. These are NOT switchblades. You open the knife slightly with the thumb stud and then the spring takes over, snapping the blade open like a switchblade. Check out these assisted opening knives, these can be opened easily with one hand and are 100% legal.
