This is one of the items on the list we do have, and by golly it’s great. Definitely not a complete replacement for carrying a proper firesteel, and it would be good to have a better knife on you outdoors, but if you like carrying backups (as I’ve already expressed I do!) this is one of those excellent investments that delivers on its promises. Great multi-tool; but I’m not going to regurgitate information – you want more about it, check out Thomas’ review of it here.
What’s the bare minimum you need to navigate across land? For most people, that would be a compass and map. A basic road map is sufficient to get a rough approximation of the lay of the land. More detailed relief maps can help plan for elevation and estimate possible water sources but they also take up more room in your pack. Waterproofed or laminated maps are also extremely helpful. Lensatic compasses are the most reliable for little money. If possible, a compass and protractor are also extremely helpful for route planning. Obviously, not as essential but nonetheless useful.
