After Z-Day, blades of all sorts will be a major part of everyone’s life. Every day you will have to use a blade for work, protection, and lots of other things. What kinds of blades and blade shapes will serve you best? In this article we’ll look at different types, sizes, and shapes of blades and their uses.

EDC Blades: (Every Day Carry)
These are blades that you carry at all times, even when carrying other blades. They can be used for many things, like: cutting food, whittling, processing game, even self defense when the need arises. They’re usually smaller folding blades, but can be smaller fixed blades. ZAC suggests one folding plain edge knife and one fully serrated folding knife.

Work Blades:
Usually a mid sized blade, usually between 9 and 15 inches, but this category can include machetes for felling trees, chopping, and polling firewood. The uses are only limited by the imagination of the user. Generally the best overall and best multi-purpose knife.

Fighting Blades:
From 10 to 48 inches, this category covers anything from boot knives to swords. Best to carry at least one blade from this category.

Single or Double edged?
This all depends on the user. For a fighting blade, double edged is preferred, but not necessary. For EDC or a work blade, a single edge is best to keep from injuring yourself during use when even a small cut can lead to infection or death if left untreated.
You will need to care for and sharpen your blades, as they can often mean the difference between life and death in a survival situation. ZAC recommends the Smith’s Tri-Hone system for sharpening. The honing oil provided with the system is OK, but spit or water works just as well and costs less.

ZAC recommends that you learn to sharpen a knife for its purpose. A general use knife doesn’t need to be razor sharp and this can lead to extended life for the blade, while over sharpening can lead to the blade failing or dulling extremely fast. Fighting knives need to be extremely sharp to serve their purpose unless they are swords. Swords need to be sharp, but not razor sharp. The weight of the sword causes a cleaving effect. Lighter swords do need to be sharper. EDC knives vary. If you use them on hard surfaces, or for prying, then a 25 degree rough edge will do fine. If you want it razor sharp for finer use, then you want an 18 degree edge. This video is a good guide to beginning sharpening.
