I had this idea the other day and I want to get some opinions to help me flesh it out a bit more than just the concept. The setting is post apocalypse. 90% of the population died off(I'll come up with how later). No one was around to keep factories going or mining so anything factory made had a finite supply. Bullets stopped being made and during the aftermath of the apocalypse they were mostly used up. Since metal used for guns is relatively high quality it was melted down and remade into other things(The hq metal being referred to as 'gunmetal'). During the 'present' when the story takes place humanity is beginning to bounce back but its reverted to a more medieval society. In it there's a training order called "The order of the Knife". It's called that because the knife is the first blade. In this order each person is trained in the use of the knife first. They must master it before they can move on to daggers and swords. High clerics of The order of the Knife are called "Blades" because they've mastered every blade the order offers training for. When they become a blade they leave the order with only a knife to go on a kind of pilgrimage to defend others. If they want more than just a knife to use they have to make it themselves or it can be a 'treasure sword', a sword found in ruins that was made before the apocalypse. The 'make or find' rule is in place because their lives depend on the quality of the blade. Blades also have a kind of apprentice called "Sheaths". They've mastered the Knife and the maintenance of edged weapons. Basically I thought up this after thinking up what kind of armor and weapons I'd have if the world ended. Obviously I'd go with blades but this is the 'design' I came up with. Leather jacket with the sleeves cut off at the elbow. Underneath long sleeve light weight chain mail shirt. Falconer's gloves with steel plating over the forearms(like gauntlets). Along the forearm a curved blade shaped like a kukri(making an elbow strike more lethal). For the legs heavy leather pants with metal greaves(shin guards) with a blade along the shin(like the forearms) and spiked steel toed boots. The idea is that they leave the order with only a knife and have to make their own tools, weapons, and armor out of what they find. Trying to make their body into a blade.
