The ULA Alpha is a six-and-a-half-inch long knife, but incredibly it weighs less than an ounce, which is great for hikers and backpackers! It’s a fixed blade, so it doesn’t fold, but it still fits nicely in the hip belt pockets of most lightweight backpacks. The blade is great for slicing meats and cheeses. And, unlike a folding knife, you can sanitize it completely after each use. If keeping pack weight low is really important to you and you prefer a solid, one-piece knife, the Alpha is an excellent choice.
