Top Five Assisted Opening Knives
Published: August 25th, 2025
Assisted-opening knives combine the quick deployment of an automatic with the control of a manual folder. The concept first emerged in 1995 when knifemaker Blackie Collins introduced the Strut-and-Cut, an innovative design inspired by the suspension system of his Ducati motorcycle. A few years later, Ken Onion brought assisted opening into the spotlight with his SpeedSafe mechanism for Kershaw, setting a new standard for smooth, one-handed deployment. Since then, brands like Kershaw, CRKT, Zero Tolerance, SOG, and Benchmade have each put their own spin on the concept, creating knives that range from slim and elegant to rugged and duty-ready. In this article, we look at five standout models that have earned their place among the most respected assisted-opening knives available today.
Kershaw
Leek
The Kershaw Leek is a long-standing favorite in the assisted-opening category, combining sleek design, fast deployment, and dependable performance. Designed by Ken Onion and released in 2003, it features a bead-blasted 3-inch Sandvik 14C28N drop point blade, offering excellent edge retention and corrosion resistance for everyday tasks. Kershaw’s SpeedSafe assisted opening mechanism provides quick, smooth, one-handed access via the flipper or ambidextrous thumb studs, making it highly practical for daily carry.
The 410 stainless steel handle is slim yet sturdy, housing a secure framelock that keeps the blade locked firmly in place. At 4 inches closed, 7 inches overall, and just 3 ounces, it’s compact, lightweight, and easy to carry. A reversible pocket clip supports multiple carry options, while a tip-lock slider adds safety when the knife is closed. The Leek remains a benchmark for assisted-opening knives, one that's valued for its blend of style, precision, and reliability.
CRKT
M16-14SFG
The CRKT M16-14SFG is a rugged assisted-opening folder designed by the late Kit Carson. Its 3.5-inch tanto blade is crafted from 1.4116 stainless steel with a desert tan titanium nitride (TiNi) coating and CRKT’s distinctive Veff serrations, engineered for slicing through rope, cord, and other tough materials with ease. The blade deploys smoothly via the Carson Flipper or ambidextrous thumb studs, and the patented AutoLAWKS secondary safety transforms the liner lock into a virtual fixed blade when engaged.
Contoured 5.34-inch desert tan G-10 handle scales provide a secure grip, while stainless steel Torx hardware adds durability. At 9.38 inches overall and 6.5 ounces, it’s a substantial knife built for hard use. A four-position stainless steel pocket clip allows versatile carry. Whether in the field or as part of an everyday kit, the M16-14SFG stands out for its strength, speed, and purposeful design.
Zero Tolerance
0350
The Zero Tolerance 0350 is another Ken Onion-designed assisted-opening folder, built with the durability and precision ZT is known for. Its 3.25-inch drop point recurve blade is crafted from CPM-S30V stainless steel for excellent edge retention and corrosion resistance, and finished with a black Tungsten Cerakote coating for a low-glare, wear-resistant surface. Kershaw’s SpeedSafe assisted opening mechanism snaps the blade into action with either the flipper or ambidextrous thumb studs, locking securely in place with a sturdy liner lock.
Black textured G-10 handle scales provide a confident grip, while the four-position pocket clip offers flexible carry options. Measuring 4.9 inches closed and 8.4 inches overall, and weighing 6.2 ounces, the 0350 delivers a solid, balanced feel without sacrificing control. Proudly made in the USA, it’s a proven choice for those who want a tough, reliable, and quick-deploying knife for everyday and tactical use.
*Older models featured a DLC coating, while newer models use Cerakote.
SOG
Flash AT (Concrete)
The SOG Flash AT is a modern assisted-opening folder built for speed, safety, and everyday versatility. Its 3.45-inch drop point blade is crafted from cryogenically treated D2 tool steel, offering excellent edge retention and wear resistance, and finished with a black titanium nitride (TiNi) coating for added corrosion protection and a low-glare, tactical look. SOG’s assisted opening system, activated via dual thumb studs, delivers fast, reliable deployment, while the AT-XR Lock provides rock-solid blade security in use.
A spine-mounted safety switch adds extra peace of mind, preventing accidental openings when carried. The concrete GRN handle is lightweight, durable, and ergonomically textured for a confident grip in all conditions. At 4.67 inches closed, 8.12 inches overall, and just 4.49 ounces, it balances substance with all-day carry comfort. A reversible deep-carry clip ensures discreet pocket carry, making the Flash AT a dependable choice for those who want tactical performance in a streamlined EDC package.
Benchmade
Barrage (Blue Canyon Richlite)
The Benchmade Barrage is a refined update to Warren Osborne’s iconic assisted-opening design, offering fast deployment, comfort, and premium materials. Its 3.6-inch drop point blade is crafted from CPM S30V stainless steel, finished in stonewash for a balanced mix of corrosion resistance and edge retention. The AXIS Assist mechanism provides quick, smooth, one-handed deployment via ambidextrous thumb studs, and an integrated spine safety adds an extra layer of security during carry and use.
This version features milled Blue Canyon Richlite handle scales that are both stylish and functional, offering durability, moisture resistance, and a comfortable grip. A reversible tip-up pocket clip provides versatile carry options. Measuring 4.8 inches closed, 8.35 inches overall, and weighing 4.45 ounces, it delivers a substantial yet manageable feel.
