The Benchmade Immunity is a carry-friendly knife legal in most states thanks to its under 2.5" blade. While small in stature, the Immunity is built like a tank thanks to its milled aluminum handles and stainless steel liners. Dual anodized thumbstuds get the blade into play quickly if you need it. Immune to most knife laws in the USA, this is a great knife for anyone looking for a small EDC knife that combines style and function.
