This knife is perfect for if Zombies were attacking and you're friend did not have a knife to defend himself. So just make him (her) one. Also It is The cheapest knife to make. I had a blast making this, and I hope you do to :)
Step 1: What You Need
Stick (mine was 7 inches long depending on how big you want it)
Saw blade & normal blade (I have a swiss army knife that had both)
First start by making a small notch were you want the blade to start. Then from that notch up start slimming the blade of you're wooden knife. slant towards one side dot his on both sides to create a pretty sharp edge.
Now at the top of the blade you are making slant up and in to create a point (almost like sharpening a pencil with a knife) After you have made a point (this is optional) sand the blade and handle it makes it look a lot better (but if zombies are attacking you don't need to do this step)
Thats all you're done. You will now have a lot of wood shavings so be creative, and don't throw them away make something with them. I hope you enjoyed this instructable, and don't forget to vote.
