Both these types of blades are commonly available as you search among the best knives on Amazon. The folding blades are ideal for EDC chores on the camp like cutting simple ropes or a few fruits and vegetables. However, look for the ones with a great locking mechanism to prevent any mishaps. The fixed blade knives are great for hard work like cutting up wood or bigger vegetables and steak. The fixed blades should get a sheath, so you do not run the risk of hurting while carrying in your pocket.
