This mainly depends on where and how you’ll be using the knife on your kayak adventure. As we mentioned earlier, fixed blades are usually much tougher. They’re a good choice for survival situations, cutting wood or when preparing your lunch. On the other hand, you can put a folding blade in your pocket, it generally weighs less and it will be more suited if you need some precision work done. We can’t really say which the best kayak knife type is, because this mainly comes down to your personal preference.
