    Affordable and high quality, only down side is that the sheath is cumbersome for such a small knife.

    The rat 3 is perfect. It’s small enough to EDC, razor sharp, and really seems like it can handle some rugged use for its size. I have been wanting one for years. I’m glad I finally pulled the trigger and got it.
