The tool for the job is the tool you have on you. No one goes to a gunfight with a pistol, they grab a shotgun. Unfortunately when we need a tool the one we have on us is usually less effective because we carry it because it is less heavy than the better tools. But, if you know enough that you will need the pocket knife for batonning, you probably have a good idea when you will need to use it, hence you can go prepared with a fixed blade or hatchet.
