There are some people who advocate the use of a small fixed blade knife carried forward of the hips. For most of us - certainly those of us in the Shivworks Collective - we do so for specific reasons, and those reasons also drive the design of the Craig Douglas ClinchPick and how it should ideally be carried with the handle at a downward diagonal angle. One of the biggest drivers of this conceptual methodology is how effective it is in an entanglement, and how there are many opportunities where you can access this kind of blade when you cannot deploy any other weapon. Rather than try to describe this in words, here is a short video showing one glaring example of how this works. It is meant not as a dogmatic "this is the move to do", but instead it is a very plausible and useful example of how to implement the technique.
