Question: Does it automatically open?
Document: It's just a little smaller than those knives that scream "weapon," though it looks all-business. That combined with its light weight mean it's always in my pocket.It's called "speed-safe" because, while it opens almost automatically, the spring actually holds it closed when it's closed. People often ask me if it can open in your pocket, but it hasn't happened to me in over a year.
I have many, many pocket knives. The Leek is the one that most often rides around in my pocket because of its sheer all-around utility. The knife is really flat so it doesn't feel bulky in my pocket and it is easy to extract from my pocket. You can truly use one hand to open it quickly and it automatically locks open. I recently broke the slide lock that keeps the blade from opening and wrote an email to the Kershaw warranty service address.
But for most emergencies, Flicking the knife open by itself may be all the conversation stopper I need.
It's sharp and easy to open one handed and has a blade lock to keep it closed in your pocket
I love this knife. Easily one of the sharpest knifes I own. Very quick to open as well.
The Ken Onion Kershaw Leek is functional, easy to sharpen, comfortable to carry, quick to open and access.
Sharp as a razor. It flips open very quickly. The fit and finish are terrific. I just hope it's not considered a switch blade!
Love this knife. Very sharp. Carry it around in my pocket and use it multiple times a day. The auto open is excellent!
It is really cool to open. I know everyone says you shouldn't play with knifes. If that's true then they shouldn't have made this one. It's that addictive.
This knife is well made and keeps edge well. It is easy to open with one hand. I have purchased five more for friends and family.
