A simple but useful knife that can be kept here and there, in your backpack, bag, car, toolbox, desk drawer or wherever you need a small knife. When pushing the blade forwards or inwards, it is best to push the latch sideways, not upwards, as this is easiest and the arm bends as little as possible for best durability. The key ring hole is made to fasten a paracord strap, so you can always have a piece of rope in your backpack along with the knife. Be careful though, knives are sharp and you can cut yourself if you are careless. 

Works with standard replacement blades for utility knives.
