It has a plastic fulcrum that the tip of the blade rides on that forces it open when you draw it out. It works really smooth and is great for when you have one hand full and you need to cut something. I mainly made it for camping because in the state where I live Fixed Blade knives are a big no, no, so now I have a knife big enough for bushcraft work that is almost as easy to use as a fixed blade.
thanks
That is a great looking sheath, have you been wearing it a lot?
