6 Best Budget Spring Assisted Knives

From collectors to avid outdoorsmen (and women), day laborers or simply those who like having a versatile tool ready at hand, spring assisted blades have skyrocketed in popularity.

Also known as assisted-opening knives, these blades are revered for their fast and reliable deployment while reducing the risk of human error and injury.

Many of us have been there, with even the most well-practiced knife-wielder experiencing a misfire from time to time with manual flipper knives. The same cannot be said for spring assisted openers. Short of catastrophic mechanical failure (a rarity), these blades deploy with unparalleled reliability.

One misconception about these blades is that you have to spend an arm and a leg to get any half-decent blade. In this guide, we dispel this myth, covering six of the BEST budget spring assisted knives on the market in 2021.

So kick back, grab a drink, and let’s dive in.
