The rules around fixed blade knives aren’t that different in most places from the laws around pocket knives and usually focus on blade size and length. Fixed blade knives also often have superior ergonomics to pocket knives. Do fixed blade knives cost less than pocket knives? In theory, a fixed blade knife is simpler to manufacture, so all else being equal, you can often find a fixed blade knife for less than an equivalent pocket knife. There are always deals to be found for fixed blade knives just like there are for folding knives, but cost isn’t one of the main reasons to consider buying a fixed blade knife.
