Myself, I already have everything I need.
Years ago I bought flint arrowheads. So I have those handy if I need them. That plus a steel knife and some suitable tinder, and I am good to go. eg. Pine sap makes very good tinder for starting a fire.
eg. Watch the following video from Coalcracker Bushcraft on how to use pine sap as tinder. Plus, pine sap is suitable tinder when everything else is wet because it is so oily it repels water.
