    They've been used before and as rocks and stones can be found almost everywhere should the need to make a weapon or tool arise you need to know how it's done.

    Choosing The Right Rocks:
    Not all rocks can be used to make knives. Flint or obsidian might be the best but if you can't find them rocks then to find if the rocks available can make good knives, knock them together. If they make a "ringing" sound then you have the right ones.

    Step Two:
    You'll need a hammer stone. These will be rocks with rounded surfaces. Rocks which don't chip easily.

    Step Three:
    Place the rock that you'll use to make a knife on a flat [but elevated] surface and strike it's edge with blows that don't stop on impact. Since the rocks are hard and brittle, the goal is to fracture the rock so it can produce a sharp blade.

    Only when the need calls for it. Should we have a nuclear apocalypse then the survivors will be thrust right back to the stone age. I wouldn't want to be around when that happens though.

    not nuclear no. but anything other than that I intend to survive.
    I think there will be plenty of metal we can strip down and sharpen to use as knives, without heaving rocks about.
    like most survivalists i'm an avid knife collector!!:p

    Well, you can find obsidian if your survivalist struggle is happening near a volcanic area. Otherwise, rocks should do. But I think that if you ever stumble upon a dire situation where you have to make knives out of stone or glass. Is pretty likely that you have to do it because you forgot to bring along a reliable knife with you rather than a Nuclear fallout taking humanity back to stone age.

    I made knives out of stone when I just started out surviving and I wasn't that prepared, it takes a long time to make them sharp and usually they come out jagged, but I was able to use it for basic tasks. They're definitely weaker than a stainless steel one.
