Spyderco Matriarch fits the bill!
I like a fixed blade knife for all purpose use BUT for city use, the Matriarch, at 5 inches overall and a 3 3/4 inch blade does all the work I need. It is flat, lightweight and easy to carry, in pocket or clipped to clothing. The blade inspires confidence, solid opening, wide blade at the base, then curves into a eagle beak confirmation. What does and eagle use his beak for: to rip and tear large chunks of meat to swallow. The Matriarch is designed to rip and tear, whether rope, cordage, a limb, or canvas or leather or denim. Hold a Matriarch in your hand, open and close the blade and you will be hooked for life with its utility! The blade is flared at the base so your thumb can put power in the cut! Handle a Matriarch and determine how many purposes it will serve. Love it!
