This is a lite weight, sturdy, razor sharp little beast that opens one handed with a simple push of button and a tiny flick of the wrist and you are ready for any situation that arises.to close simply push the same button in and the blade will easily fold and lock closed, which is also a nice feature.

When I looked at this and it says locked in the open position, i think "I hit the button, it opens." Not the case. The button is a safety you must push then pull the blade out. It is annoying to use both hands to open this, and the button is very small and hard to push, aggravating on my thumb. The blade is very sharp and sturdy though, and the handle has a light sturdy feel.
