ESEE Izula II. Can't find a fault with it. Scary sharp. Very rugged. Small enough profile that if you had to conceal it a simple t-shirt will do.
Usually carry a simple 3 blade Stockman style for about 80% of my needs. I add a Buck 110, or a tactical folder, both work well. If serious hiking, I go with a Kabar, 7in blade USMC style, and ball park pricing for a 2 knife combo price, under $125.00.
I enjoy bladed knives, and some are way more expensive than my demand is required. They are proven, even a cheapie Mora is a tool to me if needed. The real task is to keep a keen edge, and avoid rust as much as you can.
Good luck, try a few, you will find your favorite.
